that have the same native or script internally. We no longer need this hack,
given regexp cloning done for precompiled scripts and functions (i.e., those
not eval'd or compile-and-go executed via a JS_Evaluate* API).
Fix a script_compile bug found during the scan of JSFRAME_EVAL occasioned by
the instanceof fix.
Bug 254067, r=shaver@mozilla.org.

locals (169559, r=shaver).
- Also fix longstanding bug where global regexps in precompiled scripts were
wrongly shared among threads/contexts (165201, r=shaver).
- Also fix strict-aliasing gcc warning causes (206599, r=bryner).

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); }

where any occurrence of arguments.length or arguments[0], e.g., would be
"optimized" to use those bytecodes. This is just wrong if the occurrence
is an operand of delete, ++, --, or the left-hand-side of an assignment
operator!
- [jsfun.c, jsinterp.c] args_getProperty etc. must use JS_GetInstancePrivate,
not JS_GetPrivate, as the arguments object is exposed, and can be made a
prototype of other objects that do not have private data, or private data
that's a JSStackFrame*. Same goes for fun_getProperty, js_GetArgument, etc.
- [jsfun.c, jsobj.c, jsstr.c] No need to specialize fun_delProperty and
str_delProperty to help convince users and ECMA conformance tests that
fun.length and str.length are direct properties of instances, instead of
being delegated to Function.prototype.length and String.prototype.length.
This special case is done universally in js_DeleteProperty for all SHARED
and PERMANENT proto-properties.
- [jshash.c] Sneaking this followup-fix for bug 69271 in: use JS_HASH_BITS
rather than hardcoded 32.
- [jsobj.c, jsscope.[ch]] Fix misnamed js_HashValue (it takes a jsid, so it
is now js_HashId).
- [jsscript.c] script_compile needs to call JS_InstanceOf, to ensure that obj
is a Script object.

- Fix bug where script jssrcnote vector terminator was not XDRed.
- Ensure that memory is cleared by serializing zero padding bytes as needed
under JS_XDRBytes and JS_XDRString.
- Fix JS_XDRValue to handle undefined and null JS types properly (bug 31003).
Also make it cast from jsint to uint32 and back carefully, so as to work
with negative numbers even on targets where jsval is a signed 64 bit type.
- Add JS_XDRScript public API.
- Optimize the per-JSXDRState class registry so it uses a JSDHashTable upon
searching for a class-id by name in an overpopulated (for linear search)
registry table.
- Clean up API nits such as JS_XDRNewBase => JS_XDRInitBase, with parameter
list rotation to put cx last (JS_XDRInitBase is an infallible init helper,
not an error-reporting, cx-comes-first, API entry point).
- Fix some XXX comments, unneeded masks, other nits.
- Make sure all JS XDR API functions start with JS_XDR.

Backing out Brendan's previous checkin for bug #65553 (jsapi.c, jsdbgapi.c, jsemit.c, jsinterp.c, jsinterp.h, jsobj.c, and jsscript.c), so we can get smoke tests going.
