c291e2f578 Add target hook for pseudo instruction expansion. 
Many targets use pseudo instructions to help register allocation.  Like
the COPY instruction, these pseudos can be expanded after register
allocation.  The early expansion can make life easier for PEI and the
post-ra scheduler.

This patch adds a hook that is called for all remaining pseudo
instructions from the ExpandPostRAPseudos pass.

0eba4fe292 [vector-select] Address one of the issues in pr10902. EXTRACT_VECTOR_ELEMENT 
SDNodes may return values which are wider than the incoming element types. In
this patch we fix the integer promotion of these nodes.

Fixes spill-q.ll when running -promote-elements.

fb96574fca Rename LowerSubregs to ExpandPostRAPseudos. 
I'll fix the file contents in the next commit.

This pass is currently expanding the COPY and SUBREG_TO_REG pseudos. I
am going to add a hook so targets can expand more pseudo-instructions
after register allocation.

Many targets have pseudo-instructions that assist the register
allocator.  They can be expanded after register allocation, before PEI
and PostRA scheduling.

17e76bda55 Implement Duncan's suggestion to use the result of getSetCCResultType if it is legal 
(this is always the case for scalars), otherwise use the promoted result type.

0d5357e3d5 [Vector-Select] Address one of the problems in 10902. 
When generating the trunc-store of i1's, we need to use the vector type and not
the scalar type.

This patch fixes the assertion in CodeGen/Generic/bool-vector.ll when
running with -promote-elements.

Math is hard, and isScaledConstantInRange() always returned false for
negative constants.  It was doing unsigned division of negative numbers
before casting back to signed.
