If we see a f2i(UnboxDouble) chain, simplify it to UnboxInt32 which does the conversion internally. This also enables a fastpath to read 31-bit jsval integers from arrays.

Don't use a builtin for this. For functions its interned in the native frame. For global this we read from fp->thisp. Restore jsinterp.cpp and jsinterp.h (no longer need COMPUTE_THIS exposed).

Trace JSOP_THIS and JSOP_THISPROP.
...
Rename getprop to get_prop, just because.
Extract COMPUTE_THIS to jsinterp.h as JS_COMPUTE_THIS for reuse in tracer.

Specialized tracing of Math.sin, as a proof of concept. Doesn't quite work due to regalloc mismatch, but close!

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.
