TclCompileStringCmd and TclCompileReturnCmd.
* generic/tclCompile.h: Added definition of INST_STRLEN opcode and
updated LAST_INST_OPCODE value.
* generic/tclBasic.c: Added information about TclCompileStringCmd
and TclCompileReturnCmd to BuiltInCmds table.
* generic/tclExecute.c (TclExecuteByteCode): Added support for the
INST_STRLEN opcode.
* generic/tclCompCmds.c
(TclCompileStringCmd): Basic implementation of byte-compiled
[string] command. Not all subcommands are implemented; those
that are not an out-line compiled.
(TclCompileReturnCmd): Byte-compiled implementation of [return]
command. Only "simple" returns are byte-compiled; in particular,
if the -code, -errorinfo or -errorcode flags are used, the command
is not byte-compiled.

* tests/expr.test:
* tests/expr-old.test: added tests for 'eq' and 'ne'
* generic/tclExecute.c:
* generic/tclCompile.h: added INST_STREQ and INST_STRNEQ opcodes
that do strict string comparisons.
* generic/tclCompExpr.c: added 'eq' and 'ne' string comparison
operators.
* generic/tclParseExpr.c (GetLexeme): added 'eq' and 'ne' expr
parse terms (string (in)equality check).

* generic/tclNamesp.c (Tcl_Export): added a uniq'ing test to the
export list so only one instance of each export pattern would
exist in the list.
* generic/tclExecute.c (TclExecuteByteCode): optimized case for
the empty string in ==/!= comparisons

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

* tests/parseExpr.test:

* generic/tclGet.c:
* generic/tclInt.h:
* generic/tclObj.c:
* generic/tclParseExpr.c:
* generic/tclUtil.c:
* generic/tclExecute.c: added TclCheckBadOctal routine to enhance
error message checking for when users use invalid octal numbers
(like 08), as well as replumbed the Expr*Funcs with a new
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]

* generic/tclExecute.c (TclExecuteByteCode): Fixed crash caused by
a bug in INST_LOAD_SCALAR1 where the scalar index was read as
a signed 1 byte value instead of unsigned. [Bug: 2243]
