f06f6f50e9 Experimental support for aligned NEON spills. 
ARM targets with NEON units have access to aligned vector loads and
stores that are potentially faster than unaligned operations.

Add support for spilling the callee-saved NEON registers to an aligned
stack area using 16-byte aligned NEON loads and store.

This feature is off by default, controlled by an -align-neon-spills
command line option.

f4aea8f349 Add variants of the dispatchsetup pseudo for Thumb and !VFP. <rdar://10620138> 
My change r146949 added register clobbers to the eh_sjlj_dispatchsetup pseudo
instruction, but on Thumb1 some of those registers cannot be used.  This
caused massive failures on the testsuite when compiling for Thumb1.  While
fixing that, I noticed that the eh_sjlj_setjmp instruction has a "nofp"
variant, and I realized that dispatchsetup needs the same thing, so I have
added that as well.

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.

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.
