01442cd1b9 Reenable building with -fvisibility-inlines-hidden. 
This was disabled years ago because of a bug in GCC 4.1, which is
on our "broken compilers" list for other reasons. Saving ~500k
on a clang binary (Release+Asserts) is well worth dropping support
for it.

We currently disable it for shared libraries (where it would bring
the biggest win) because clang is broken (PR11642).

IMPORTANT: If you're doing incremental builds you may get tons of
linker warnings. make clean will fix them.

f1eba25303 Reinstate r146578; it doesn't appear to be the cause of some recent execution- 
time regressions.  In general, it is beneficial to compile-time.

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

c7448f8d47 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.

51f40a725b 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.

de4d83943a 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.
