there is a reason to move their definitions to the header and make them truly

Mark a few more pattern-less instructions with neverHasSideEffects. This is especially important on instructions like t2LEApcreal which are prime candidate for machine LICM.

Intrinsics which do a vector compare (results are all zero or all ones) are modeled as icmp / fcmp + sext. This is turned into a vsetcc by dag combine (yes, not a good long term solution). The targets can then isel the vsetcc to the appropriate instruction.

The trouble arises when the result of a vector cmp + sext is then and'ed with all ones. Instcombine will turn it into a vector cmp + zext, dag combiner will miss turning it into a vsetcc and hell breaks loose after that.

Teach dag combine to turn a vector cpm + zest into a vsetcc + and 1. This fixes rdar://7923010.

The register use operands (e.g. the first argument is passed in a 
register) is currently being modeled as a normal register use,
instead of correctly being an implicit use.  This causes the operand
to get propagated onto the mcinst, which was causing the encoder to
emit a rex prefix byte, which generates an invalid call.

This fixes rdar://7998435

Sink dag combine's post index load / store code that swap base ptr and index into the target hook. Only the target knows whether the swap is safe. In Thumb2 mode, the offset must be an immediate. rdar://7998649
