5b6d21503b Cleanup PromoteIntOp_EXTRACT_VECTOR_ELT and PromoteIntRes_SETCC. 
Add a new method: getAnyExtOrTrunc and use it to replace the manual check.

1d08f41853 Revert r140463; The patch assumes that <4 x i1> is saved to memory as 4 x i8, 
while the decision is to bit-pack small values.

eb2bea7d4a Disable LSR retry by default. 
Disabling aggressive LSR saves compilation time, and with the new
indvars behavior usually improves performance.

4dfc60fab6 LSR cost metric minor fix and verification. 
The minor bug heuristic was noticed by inspection. I added the
isLoser/isValid helpers because they will become more
important with subsequent checkins.

6aaaadc188 Convert more tests over to the new atomic instructions. 
I did not convert Atomics-32.ll and Atomics-64.ll by hand; the diff is autoupgrade output.

The wmb test is gone because there isn't any way to express wmb with the new atomic instructions; if someone really needs a non-asm way to write a wmb on Alpha, a platform-specific intrisic could be added.

cbd2c336ab 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.

559e12a58a [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.

e5f42e93f7 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.

(this is always the case for scalars), otherwise use the promoted result type.

f1449d75ba [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.
