e93d99cf07 Remove Synthesizable from the Type system; as MMX vector 
types are no longer Legal on X86, we don't need it.
No functional change.  8499854.

aa9d854b33 Revert r97064. Duncan pointed out that bitcasts are defined in 
terms of store and load, which means bitcasting between scalar
integer and vector has endian-specific results, which undermines
this whole approach.

c382bc3c0f Make getTypeSizeInBits work correctly for array types; it should return 
the number of value bits, not the number of bits of allocation for in-memory
storage.

Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and
vectors.

Fix several places in CodeGen which compute offsets into in-memory vectors
to use TargetData information.

This fixes PR1784.

f7ea6c3ee8 The previous fix of widening divides that trap was too fragile as it depends on custom 
lowering and requires that certain types exist in ValueTypes.h.  Modified widening to
check if an op can trap and if so, the widening algorithm will apply only the op on
the defined elements.  It is safer to do this in widening because the optimizer can't
guarantee removing unused ops in some cases.

d199636039 Revert an earlier change to SIGN_EXTEND_INREG for vectors. The VTSDNode 
really does need to be a vector type, because
TargetLowering::getOperationAction for SIGN_EXTEND_INREG uses that type,
and it needs to be able to distinguish between vectors and scalars.

Also, fix some more issues with legalization of vector casts.

ff89dcb06f -Revert parts of 84326 and 84411. Distinquishing between fixed and non-fixed 
stack slots and giving them different PseudoSourceValue's did not fix the
problem of post-alloc scheduling miscompiling llvm itself.
- Apply Dan's conservative workaround by assuming any non fixed stack slots can
alias other memory locations. This means a load from spill slot #1 cannot 
move above a store of spill slot #2. 
- Enable post-alloc scheduling for x86 at optimization leverl Default and above.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.

"UREACHABLE executed").
