Kevin Enderby b9783dd9bc Added a handful of x86-32 instructions that were missing so that llvm-mc would 
be more complete.  These are only expected to be used by llvm-mc with assembly
source so there is no pattern, [], in the .td files.  Most are being added to
X86InstrInfo.td as Chris suggested and only comments about register uses are
added.  Suggestions welcome on the .td changes as I'm not sure on every detail
of the x86 records.  More missing instructions will be coming.

Rafael Espindola 3521f8467d Produce a R_386_PLT32 when needed. Moved the default cases of switches to the 
start for consistency.

Jim Grosbach 00fe92da6b ARM addrmode4 instructions (ldm, stm and friends) can't encode an immediate 
offset for stack references. Make sure we take that into account when
deciding whether to reserver an emergency spill slot for the register
scavenger. rdar://8559625

Kalle Raiskila 5f2034c455 Improve lowering of sext to i128 on SPU. 
The old algorithm inserted a 'rotqmbyi' instruction which was
both redundant and wrong - it made shufb select bytes from the
wrong end of the input quad.
