input/output patterns have the same type.  It turns out that 
this triggers all the time because we don't infer types 
between these boundaries.  Until we do, don't turn this on.

then use it as an MMX register (!?).

this is tidier and can find bugs.

though some look dubious afaict, these are all ok.

This fixes CodeGen/X86/x86-64-and-mask.ll

don't alis it in the MMX .td file with a different width,
split into two X86ISD opcodes.  This fixes an x86 testcase.

this lowering at isel time instead of in legalize.  This fixes fcmp64.ll

ridiculously ginormous patterns and need more than one byte
of displacement for encodings.  This fixes CellSPU/fdiv.ll.
SPU is still doing something else ridiculous though.

Instcombine constant folding can normalize gep with negative index to index with large offset. When instcombine objsize checking transformation sees these geps where the offset seemingly point out of bound, it should just return "i don't know" rather than asserting.

well as the operands produced when the pattern is matched.  This
allows CheckSame to work correctly when matching replicated 
names involving ComplexPatterns.  This fixes a bunch of MSP430 
failures, we're down to 13 failures, two of which are
due to a sched bug.

126.gcc nightly tests. These failures uncovered latent bugs that machine DCE
could remove one half of a stack adjust down/up pair, causing PEI to assert.
This update fixes that, and the tests now pass.
