Benjamin Kramer 7adb189538 InstCombine: When comparing two GEPs that were derived from the same base pointer but use different types, expand the offset calculation and to the compare on the offset if profitable. 
This came up in SmallVector code.

Benjamin Kramer 7746eb62fb InstCombine: Make OptimizePointerDifference more aggressive. 
- Ignore pointer casts.
- Also expand GEPs that aren't constantexprs when they have one use or only constant indices.

- We now compile "&foo[i] - &foo[j]" into "i - j".

Chandler Carruth a2a5410e6d Add 3dNOW intrinsic header to x86intrin.h, conditioned on __3dNOW__ to 
match the behavior of GCC. Also add a test for these intrinsics, which
apparently have *zero* tests. =[ Not surprisingly, Clang crashed when
compiling these.

Fix the bug in CodeGen where we failed to bitcast the argument type to
x86mmx prior to calling the LLVM intrinsic. This fixes an assert on the
new 3dnow-builtins.c test.

This is one issue impacting the efforts to get Clang to emulate the
Microsoft intrinsics headers -- 3dnow intrinsics are implictitly made
available there.

Chris Lattner 445d8c6b50 fold comparisons of gep'd alloca points with null to false, 
implementing PR12013.  We now compile the testcase to:

instead of:

	pushq	%rbx

	ret

This doesn't shrink clang noticably though.
