API compatibility JS_GetStringBytes(JSString *str) calls newly introduced
js_GetGCStringRuntime(JSString *str) to extract JSRuntime* instance based
on the layout of GC structures. r=brendan
- Add JS_ReportPendingException, and fix its js_ReportUncaughtException subroutine to (a) not return false on vacuous success; (b) fail to clear the pending exception it reports.
The latter no longer calls the former via js_ConstructObject, to
minimize failure opportunities when converting an error into an
exception. Also, the 'stack' property of exception objects
faithfully preserves Unicode in function names and decompiled
actual argument sources.
Also, fun_xdrObject was reversing property order when encoding;
fixed to maximize property tree compression gain.
Also^2, js_ConstructObject was not handling success+not-found
return from FindConstructor.

with JSRESOLVE_ASSIGNING, wrongly), plus a few miscellaneous bugfixes.
- Combine the JSStackFrame members constructing, special, overrides, and
reserved into a uint32 flags member.
- Separate JOF_ASSIGNING from the JOF_SET bytecode format flag, and impute
JSRESOLVE_ASSIGNING from the presence of JOF_ASSIGNING among the current
opcode's format flags. To handle the for-in loop opcodes, which do more
than simply assign -- in particular, they do property lookups whose resolve
hook outcalls should not be flagged with JSRESOLVE_ASSIGNING -- a new frame
flag, JSFRAME_ASSIGNING, has been added.
- Fix interpreter version selection to respect JS_SetVersion, whose effect on
cx->version is "sticky".
- Fix js_DecompileValueGenerator to deal with JSOP_ENUMELEM -- it never had,
as this testcase shows (it crashes without this patch):
version(120);
eval("function fe(s) { for (it[s] in this); }");
try { fe('rdonly'); } catch (e) { print(e); }

His comments:
Here are the changes to JSRef to make it compile either as C or C++. Mostly the changes are to add missing casts (since C++ doesn't have implict conversion from void* to other pointer types nor implicit casts from ints to enumerations) plus a few random things like the use of "private" as a variable name.
There are a few other minor bug fixes; in particular:
* A long statement with and'ed conditions is reformatted to make it easier to remove other builtin objects (e.g. Date).
* A #if was added to jsscript.c for the JS_HAS_SCRIPT_OBJECT off case.
* In jsmath a #ifdef was changed to #if.
My notes also mention...
* jsobj.c should include jsopcode.h
* jsfun.c - doesn't link if JS_HAS_ARGS_OBJECT is off
* jsarray.c - a reference to js_ValueToSource should be conditional on JS_HAS_TOSOURCE
