d16131e35c Reinstate r146578; it doesn't appear to be the cause of some recent execution- 
time regressions.  In general, it is beneficial to compile-time.

Original commit message:
Fix for bug #11429: Wrong behaviour for switches. Small improvement for code
size heuristics.

06dffd2643 ARM VFP add encoding of the bitcount to fixed-point<-->floating point. insns. 
The value from the operands isn't right yet, but we weren't encoding it at
all previously. The parser needs to twiddle the values when building the
instruction.

acdf352b77 Make the unreachable probability much much heavier. The previous 
probability wouldn't be considered "hot" in some weird loop structures
or other compounding probability patterns. This makes it much harder to
confuse, but isn't really a principled fix. I'd actually like it if we
could model a zero probability, as it would make this much easier to
reason about. Suggestions for how to do this better are welcome.

88eacffd72 ARM asm parser should be more lenient w/ .thumb_func directive. 
Rather than require the symbol to be explicitly an argument of the directive,
allow it to look ahead and grab the symbol from the next non-whitespace
line.
