are not visible in script's, to properly account for them while
counting lines for #280, during direct and compiled execution.

TclArgumentBCRelease, TclArgumentGet):
* generic/tclCompile.c (EnterCmdWordIndex, TclCleanupByteCode,
TclInitCompileEnv, TclCompileScript):
* generic/tclCompile.h (ExtCmdLoc):
* generic/tclExecute.c (TclExecuteByteCode):
* generic/tclInt.h (ExtIndex, CFWordBC):
* tests/info.test (info-39.0):
Backport of some changes made to the Tcl head, to handle literal
sharing better. The code here is much simpler (trimmed down)
compared to the head as the 8.4 branch is not bytecode compiling
whole files, and doesn't compile eval'd code either.
Reworked the handling of literal command arguments in bytecode to
be saved (compiler) and used (execution) per command (See the
TCL_INVOKE_STK* instructions), and not per the whole bytecode.
This removes the problems with location data caused by literal
sharing in proc bodies. Simplified the associated datastructures
(ExtIndex is gone, as is the function EnterCmdWordIndex).

* generic/tclProc.c: when compiling a proc survives too long. We
* tests/execute.test: only need it there long enough for the right
TclInitCompileEnv() call to re-stash it into envPtr->procPtr. Once
that is done, the CompileEnv controls. If we let the value of
iPtr->compiledProcPtr linger, though, then any other bytecode compile
operation that takes place will also have its CompileEnv initialized
with it, and that's not correct. The value is meant to control the
compile of the proc body only, not other compile tasks that happen
along. Thanks to Carlos Tasada for discovering and reporting the
problem. [Bug 2802881].

word index when deleting an interpreter (DeleteInterpProc). Added
missing ref count when creating an empty string as path (EvalEx).
* generic/tclCompile.c (TclInitCompileEnv): Made same change to
control flow as in TclEvalObjEx. Not needed while uplevel and
siblings go through the eval-direct code path, however if that
changes (like it did in 8.5+) better to have this in place instead
of re-searching why certain places are without absolute locations.
* tests/info.test: Added tests 38.*, exactly testing the tracking
of location for uplevel scripts, and made the testsuite fully
usable with and without -singleproc 1.

* generic/tclCmdIL.c: immediately, without search. Reworked setup
* generic/tclCompile.c: of eoFramePtr, doesn't need the line
* tests/info.test: information, more sensible to have everything
on line 1 when eval'ing a pure list. Updated the users of the line
information to special case this based on the frame type (i.e.
TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new
behaviour.

* generic/tclCompile.c: for #280 to fix the abysmal performance
* generic/tclCompile.h: for deep recursion, replaced the linear
* generic/tclExecute.c: search through the whole stack with
* generic/tclInt.h: another hashtable and simplified the data
structure used by the compiler (array instead of hashtable).
Incidentially this also fixes the memory leak reported via [Bug
2024937].

* doc/CrtSlave.3: the string it is parsing, so it is no
* doc/CrtTrace.3: longer necessary for Tcl_Eval() to be
* doc/Eval.3: given a writable string. Also, the
* doc/ExprLong.3: refactoring of the Tcl_*Var* routines

* generic/tcl.h all possible source incompatibilities with
* generic/tclBasic.c the 8.3 version of the header file(s).

Added to internal stubs table. Tclcompiler (Tclpro project)
needs them if used as loadable package under Windows. Changed
signatures. We don't want to describe compiler internal
structures in "tclInt.h".

command initialization.
* generic/tclCompCmds.c: added new compile commands for append,
lappend, lindex and llength. Refactored set and incr compile
commands to use new TclPushVarName function for handling the
varname component during compilation (also used by append and
lappend). Changed string compile command to compile toplevel code
as well (when possible).
* generic/tclCompile.c: added new instruction enums
* generic/tclCompile.h: added debug info for new instructions
* generic/tclExecute.c (TclExecuteByteCode): moved elemPtr to
toplevel var (oft-used). Added definitions for new bytecode
instructions INST_LIST_INDEX, INST_LIST_LENGTH, INST_APPEND_SCALAR1,
INST_APPEND_SCALAR4, INST_APPEND_ARRAY1, INST_APPEND_ARRAY4,
INST_APPEND_ARRAY_STK, INST_APPEND_STK, INST_LAPPEND_SCALAR1,
INST_LAPPEND_SCALAR4, INST_LAPPEND_ARRAY1, INST_LAPPEND_ARRAY4,
INST_LAPPEND_ARRAY_STK, INST_LAPPEND_STK.
Refactored repititious code for reuse with INST_LOAD_STK (same as
INST_LOAD_SCALAR_STK), INST_STORE_STK (same as
INST_STORE_SCALAR_STK).
Updated INST_STR_CMP with style of fix of 2001-04-06 Fellows
[Bug #219201] as that fix only affected the runtime eval'ed
"string" (string compare is normally byte-compiled now). We
may want to back these out for speed in the future, noting the
problems with \x00 comparisons in the docs.
* generic/tclInt.h: declarations for new compile commands.
* generic/tclVar.c: change TclGetIndexedScalar,
TclGetElementOfIndexedArray, TclSetElementOfIndexedArray and
TclSetIndexedScalar to use flags. The Set functions now support
TCL_APPEND_ELEMENT and TCL_LIST_ELEMENT as well.
* generic/tclInt.decls:
* generic/tclIntDecls.h: minor signature changes for above.

INST_STRNEQ -> INST_STR_NEQ
* generic/tclCompile.c: added streq, strneq, strcmp, strlen &
strmatch to the compiled stats instructionTable
* generic/tclCompile.h: added instructions INST_STR_CMP,
INST_STR_INDEX, INST_STR_MATCH
* generic/tclCompCmds.c: added byte compiler support for
[string compare|match|index].
* generic/tclExecute.c:
Changed INST_STR_(N)EQ to return an Int object and not bother
trying to reuse the top stack object.
Added INST_STR_CMP, INST_STR_INDEX, INST_STR_MATCH bytecode ops.
Extended evalstats output info with Tcl_IsShared stat info.

* generic/tclCompile.c: fixed problem where setting to {} array
would intermittently not work. (Fontaine) [Bug: 3339]
* generic/tclCmdMZ.c:

recognize boolean objects. (Spjuth) [Bug: 2815]
* tests/info.test:
* tests/parseOld.test:
* generic/tclCmdAH.c:
* generic/tclProc.c: changed Tcl_UplevelObjCmd (uplevel) and
Tcl_EvalObjCmd (eval) to use TCL_EVAL_DIRECT in the single arg
case as well, to take advantage of potential pure list input
optimization. This means that it won't get byte compiled though,
which should be acceptable.
* generic/tclBasic.c: made Tcl_EvalObjEx pure list object aware in
the TCL_EVAL_DIRECT case for efficiency.
* generic/tclUtil.c: made Tcl_ConcatObj pure list object aware,
and return a list object in that case [Bug: 2098 2257]
* generic/tclMain.c: changed Tcl_Main to not constantly reuse the
commandPtr object (interactive case) as it could be shared. (Fellows)

VerifyExprObjType to simplify type handling.
* tests/expr.test:
* generic/tclCompile.c: fixed 'bad code length' error for
'expr + {[incr]}' case, with new test case [Bug: 3736]
and seg fault on 'expr + {[error]}' (different cause) that
was caused by a correct optimization that didn't correctly
track how it was modifying the source string in the opt.
The optimization was removed, which means that:
expr 1 + {[string length abc]}
will be not be compiled inline as before, but this should be
written:
expr {1 + [string length abc]}
which will be compiled inline for speed. This prevents
expr 1 + {[mindless error]}
from seg faulting, and only affects optimizations for
degenerate cases [Bug: 3737]
