	ChangeLog 
Log Message:
	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:
	* generic/tclUtf.c: added TclpUtfNcmp2 private command that
	mirrors Tcl_UtfNcmp, but takes n in bytes, not utf-8 chars.  This
	provides a faster alternative for comparing utf strings	internally.
	(Tcl_UniCharNcmp, Tcl_UniCharNcasecmp): removed the explicit end
	of string check as it wasn't correct for the function (by doc and
	logic).

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): reworked the string equal
	comparison code to use TclpUtfNcmp2 as well as short-circuit for
	equal objects or unequal length strings in the equal case.
	Removed the use of goto and streamlined the other parts.

	* generic/tclExecute.c (TclExecuteByteCode): added check for
	object equality in the comparison instructions.  Added
	short-circuit for != length strings in INST_EQ, INST_NEQ and
	INST_STR_CMP.  Reworked INST_STR_CMP to use TclpUtfNcmp2 where
	appropriate, and only use Tcl_UniCharNcmp when at least one of the
	objects is a Unicode obj with no utf bytes.
