* tests/parse.test (parse-15.60): routine has no mechanism to

* generic/tclCompile.c: TCL_TOKEN_EXPAND_WORD tokens representing
* generic/tclCompile.h: expanded literal words. These sections were
mostly in place to enable [info frame] to discover line information
in expanded literals. Since the parser now generates a token for
each post-expansion word referring to the right location in the
original script string, [info frame] gets all the data it needs.
* generic/tclInt.h: Revised the parser so that it never produces
* generic/tclParse.c: TCL_TOKEN_EXPAND_WORD tokens when parsing an
* tests/parse.test: expanded literal word; that is, something like
{*}{x y z}. Instead, generate the series of TCL_TOKEN_SIMPLE_WORD
tokens to represent the words that expansion of the literal string
produces. [RFE 1725186]

that builds a parse tree instead of operating with deep recursion.
This corrects reports of stack-blowing crashes parsing long
expressions [Bug 906201] and replaces a fundamentally O(N^2)
algorithm with an O(N) one [RFE 903765]. The new parser is better
able to generate error messages that clearly report both the nature
and context of the syntax error [Bugs 1029267, 1381715]. For now,
the code for the old parser is still present and can be activated
with a "#define OLD_EXPR_PARSER 1". This is for the sake of a clean
implementation patch, and for ease of benchmarking. The new parser
is non-recursive, so much lighter in stack consumption, but it
does use more heap, so there may be cases where parsing of long
expressions that succeeded with the old parser will lead to out
of memory panics with the new one. There are still more improvements
possible on that point, though significant progress may require
changes to the Tcl_Token specifications documented for the public
Tcl_Parse*() routines.
***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the
exact (usually terrible) error messages generated by the old parser.
This includes a large number of tests in the test suite.
* generic/tclInt.h: Replaced TclParseWhiteSpace() with
* generic/tclParse.c: TclParseAllWhiteSpace() which is what
* generic/tclParseExpr.c: all the callers really needed.
Breaking whitespace runs at newlines is useful only to the command
parsing function, and it can call the file scoped routine
ParseWhiteSpace() to do that.
* tests/expr-old.test: Removed knownBug constraints that masked
* tests/expr.test: failures due to revised error messages.
* tests/parseExpr.test:

Substantial refactoring of Tcl_SubstObj to make use of the same
parsing and substitution procedures as normal script evaluation.
Tcl_SubstObj() moved to tclParse.c. New routine TclSubstTokens()
created in tclParse.c which implements all substantial functioning
of Tcl_EvalTokensStandard(). TclCompileScript() loses its
"nested" argument, the Tcl_Interp struct loses its termOffset
field and the TCL_BRACKET_TERM flag in the evalFlags field, all
of which were only used (indirectly) by Tcl_SubstObj(). Tests
subst-8.7,8.8,11.4,11.5 modified to accomodate the only behavior
change: reporting of parse errors now takes precedence over
[return] and [continue] exceptions. All other behavior should
