Jakob Stoklund Olesen df977fedb6 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.

Nadav Rotem 2279949129 [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.

Jakob Stoklund Olesen f152df1e6b 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.

Nadav Rotem c2deabd202 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.

Fix test/CodeGen/X86/vsplit-and.ll when promote-elements is enabled.

Nadav Rotem 77426a754b [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.

Andrew Trick 8b2fe2f744 LSR minor bug fix in RateRegister. 
No test case. Noticed by inspection and I doubt it ever affects the
outcome of the overall heuristic, let alone final codegen.

Jakob Stoklund Olesen 2056d15bd9 Also match negative offsets for addrmode3 and addrmode5. 
Math is hard, and isScaledConstantInRange() always returned false for
negative constants.  It was doing unsigned division of negative numbers
before casting back to signed.

Garrison Venn 0a2eb8d35d Modified demo to use 3.0 resume instruction vs calling _Unwine_Resume. 
Also conducted some reformatting. As the LLVM coding standard doc does not
seem to touch on how to align function arguments, and format code longer than
80 cols in general, the confusion persists. There is the golden rule, but as
this code has gone through several styles to deal with this, the golden rule
seems to be ignored. The latest reformatting effort tries to match the other
source files as much as possible.

Tested on OS X 10.7.1 with, and without the OLD_EXC_SYSTEM defined. Have NOT
tested on LINUX.
