several things that were neither in an anonymous namespace nor static
but not intended to be global.

Teach X86 a few more vsetcc patterns.  Custom lowering for unsupported ones is next.

llvm-svn: 51009

Xform bitconvert(build_pair(load a, load b)) to a single load if the load locations are at the right offset from each other.

if those blocks consist entirely of common instructions;
merging will not add an extra branch in this case.

"is{Trivially,Really}ReMaterializable" methods.

semantically identical, but little difference in
either results or execution speed; but it's much
easier to read, at least IMO.

Hard code CmpInst back to i1 for now while I go track down what in the bitcode reader/writer is assuming i1
This was breaking a bunch of tests

This is necessary to unbreak the build.

The rest of this patch is code cleanup.

Move the various analyses used by GVN into static variables so we don't have to keep passing them around or refetching them.

SCCP like sparse lattice analysis with relative ease.  Just pick your
lattice function and implement the transfer function and you're good.
Just make sure you don't break monotonicity ;-)

include backslashes on Windows. This should fix llvm-ld problems on win32.

side effects of getName() are still evaluated.  Just call getNameSTart,
which is close enough and doesn't cause heap traffic.

llvm-gcc does not currently use VAArgInst; it lowers va_arg in the
front-end.

If all sources of a PHI node are defined by an implicit_def, just emit an implicit_def instead of a copy.

 - Comment fixes.
 - Moar whitespace.
 - Made ivars "private" by default.
No functionality change.
