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).

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

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.

Root all strings and objects first when unboxing. Then box values that might trigger the GC (doubles/ints). This probably needs some performance tuning over time.
