Reapply r139247: Cache intermediate results during traceSiblingValue.

In some cases such as interpreters using indirectbr, the CFG can be very
complicated, and live range splitting may be forced to insert a large
number of phi-defs.  When that happens, traceSiblingValue can spend a
lot of time zipping around in the CFG looking for defs and reloads.

This patch causes more information to be cached in SibValues, and the
cached values are used to terminate searches early.  This speeds up
spilling by 20x in one interpreter test case.  For more typical code,
this is just a 10% speedup of spilling.

The previous version had bugs that caused miscompilations. They have
been fixed.

Fix atomic load and store on x86 to pass -verify-machineinstrs (and possibly fix some subtle bugs involving passes which check mayStore()).

This isn't exactly ideal, but it is good enough for the moment.

Thumb2 ldm/stm 'db' mnemonics don't have a '.w' suffix.

There is no 16-bit wide encoding, so the .w suffix isn't needed (indeed, isn't
documented as allowed). Also add the missing '!' token on the _UPD

Thumb2 parsing and encoding for LDMIA.

Choose 32-bit vs. 16-bit encoding when there's no .w suffix in post-processing
as match classes are insufficient to handle the context-sensitiveness of
the writeback operand's legality for the 16-bit encodings.

When inlining exception handling code into another function, ensure that
duplicate tests are eliminated (for example if the two functions both have
a catch clause catching the same type, ensure the redundant one is removed).
Note that it would probably be safe to say that eh.typeid.for is 'const',
but since two calls to it with the same argument can give different results
(but only if the calls are in different functions), it seems more correct to
mark it only 'pure'; this doesn't get in the way of the optimization.
