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.

Generate a list of interned global slots (gslots) when we process the tree header. This list is then used whenever we iterate over the native frame. This is faster and safer than looking up properties in the global object every time.

Added a callstack that will track the pc of the call that caused a function call to be inlined. This is necessary to recover from deep side exits inside inline functions. The callstack is subject to store elimination, so unnecessary stores to the stack will go dead automatically during compilation (i.e. if we inline a function that doesn't have side exits.)

5 hours of debugging, and 9 keystrokes to fix it. That was one expensive bug. shaver's reduced fannkuch example works now. I think independently of this one we don't check properly for index underflow in dense arrays. Shaver is going to have to take a look at that (this fix makes fannkuch indexes not become negative, but doesn't explain why we crash so hard if they do become negative).

Don't demote u2f conversions and sink the type cast into the side exit type map, because this loses the sign bit for unsigned values. We could fix this by adding an explicit unsigned type to the map, but for now I think we should stick to int/double only since there is the risk of fanning out trees. Crypto doesn't seem to use ush all that much so we should be ok performance-wise.

1. Fix !JS_THREADED_INTERP bugs in BRANCH and recording switch case generation.
...
2. Rename TraceRecorder op methods to record_JSOP_xxx to avoid shadowing JSOP_*
enumerators used inside jsopcode.h macros -- death to ::JSOP_*!
3. Added atoms TraceRecorder member for giant literal pool scripts.
4. Condition assert in TraceRecorder::test_property_cache_direct_slot to avoid
false positive when executing function code accessing a global.
