Kind of an Array initialiser tour-de-force for bug 452878:
...
1. Split FastNewArray from FastNewObject built-in for greater speed/specialization and further splitting into Array_1str, etc.
2. Add Array_1str, Array_2obj, and Array_3num builtins for benchmarked new Array(...) constructions.
3. Export ARRAY_SET_DENSE_LENGTH and ARRAY_GROWBY via jsarray.h to jstracer.cpp.
4. Tweaked SetArrayElement to make common/best case code be the predicted/prefetched path.
5. js_MakeArraySlow now preserves the pre-slow length in JSSLOT_ARRAY_COUTN as a jsval-tagged int if possible -- this will help the tracer avoid aborting on dense arrays that turned slow but not sparse by addition of a named property.
6. Export js_fun_apply and js_Object from their respective .cpp files, in these cases just to jstracer.cpp via local prototypes (no .h files involved).
7. More INS_CONSTPTR and INS_CONST macrology for better names in trace debug spew.
8. Fix TraceRecorder::test_property_cache to avoid aborting on JSOP_SETNAME that creates a new global, by setting it to undefined so it can be lazily imported. This helps 3d-raytrace.js, which has an unintended global loop control variable in a function.
9. JSTraceableNative loses its premature-deadwood tclasp member (my bad).
10. TraceRecorder::record_JSOP_NEW() handles 'new Object' now along with the 'new Array' variations. I also cut down the copy-paste code from JSOP_CALL's record method to mostly what is needed now.
11. Add KNOWN_NATIVE_DECL macro for concise prototype of library-private js_* native functions, and alphabetized the lists (too long for any other order to be winning).
12. Big honking special case for foo.apply(obj, [str]), which we can generalize as needed. Helps string-tagcloud.js. What's cool is how tracing allows us to rewrite this to foo(str) with this set to obj, eliminating the Function.prototype.apply. This requires some rewriting in JSOP_ENDINIT's record method.

Move the type level from int/double to number. All traces start out as double in all slots, and denote and promote to/from int as needed. The FuncFilter optimizes on-trace casting and elininates redundant f->i-> chains. More optimization needed on this of course, and this code is now a bit slower than the previous integer-register use. However, this does solve the q += 2.5 issues. The heap access code does not properly cast yet and is likely unstable.

Added support for semi-stable loop variables. Compiling for(...) q += 2.5; is ridiculously difficult because it flip-flops between int and double. Add support to promote integer values to doubles at the loop tail if at loop entry we expect a double. Since this isn't possible the other way around, we have to get luck that we catch a path into the loop where q is already double. For this we add 3 trigger points (10, 13, 37). We will try three times to record a trace at those iteration counts of a loop. If none succeed the loop is blacklisted. This probably needs more tuning down the road.

Add helpers for i->f and f->i conversion. The f->i path goes via builtin calls.
