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.

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.

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.

No test case. Noticed by inspection and I doubt it ever affects the
outcome of the overall heuristic, let alone final codegen.

PR10998: It is not legal to sink an instruction past the terminator of a block; make sure we don't do that.

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

Post-index loads/stores in still need to print the post-indexed immediate, even if it's zero, to distinguish them from non-post-indexed instructions.

hadd/hsub intrinsics into the new fhadd/fhsub X86 node.

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.

DecomposeMERGE_VALUES to "know" that results are legalized in
a particular order, by passing it the number of the result
being legalized (the type legalization core provides this, it
just needs to be passed on).
