39ceb471b7 don't turn (A & (C0?-1:0)) | (B & ~(C0?-1:0)) -> C0 ? A : B 
for vectors.  Codegen is generating awful code or segfaulting
in various cases (e.g. PR6204).

8e76764de8 add one more bitfield optimization, allowing clang to generate 
good code on PR4216:

_test_bitfield:                                             ## @test_bitfield
	orl	$32962, %edi
	movl	$4294941946, %eax
	andq	%rdi, %rax
	ret

instead of:

_test_bitfield:
        movl    $4294941696, %ecx
        movl    %edi, %eax
        orl     $194, %edi
        orl     $32768, %eax
        andq    $250, %rdi
        andq    %rax, %rcx
        movq    %rdi, %rax
        orq     %rcx, %rax
        ret

Evan is looking into the remaining andq+imm -> andl optimization.

e4412c1f0b implement an instcombine xform needed by clang's codegen 
on the example in PR4216.  This doesn't trigger in the testsuite,
so I'd really appreciate someone scrutinizing the logic for
correctness.

546d63176e Optimize pointer comparison into the typesafe form, now that the backends will 
handle them efficiently. This is the opposite direction of the transformation
we used to have here.

0b178e25c4 remove the instcombine transformations that are inserting nasty 
pointer to int casts that confuse later optimizations.  See PR3351
for details.

This improves but doesn't complete fix 483.xalancbmk because llvm-gcc
does this xform in GCC's "fold" routine as well.  Clang++ will do
better I guess.

dyn_castNotVal, not m_Not.

strings in the input filename.
