Craig Topper e57b49ee16 Add mcpu to tests to prevent them from using AVX instructions on Sandy Bridge after r155618. 
llvm-svn: 155696

Craig Topper d0271b27cb Fix 128-bit ptest intrinsics to take v2i64 instead of v4f32 since these are integer instructions.

Chris Lattner 9edf3f50bf improve the setcc -> setcc_carry optimization to happen more 
consistently by moving it out of lowering into dag combine.

Add some missing patterns for matching away extended versions of setcc_c.

Chris Lattner 94656b1c8c fix the buildvector->insertp[sd] logic to not always create a redundant 
insertp[sd] $0, which is a noop.  Before:

_f32:                                   ## @f32
	pshufd	$1, %xmm1, %xmm2
	pshufd	$1, %xmm0, %xmm3
	addss	%xmm2, %xmm3
	addss	%xmm1, %xmm0
                                        ## kill: XMM0<def> XMM0<kill> XMM0<def>
	insertps	$0, %xmm0, %xmm0
	insertps	$16, %xmm3, %xmm0
	ret

after:

_f32:                                   ## @f32
	movdqa	%xmm0, %xmm2
	addss	%xmm1, %xmm2
	pshufd	$1, %xmm1, %xmm1
	pshufd	$1, %xmm0, %xmm3
	addss	%xmm1, %xmm3
	movdqa	%xmm2, %xmm0
	insertps	$16, %xmm3, %xmm0
	ret

The extra movs are due to a random (poor) scheduling decision.

Eric Christopher dce1e4949e Add a couple more tests for the ptest intrinsics to make sure we're 
grabbing them all correctly.

Eric Christopher f7802a33ce Add support for gcc __builtin_ia32_ptest{z,c,nzc} intrinsics. Lower 
to ptest instruction plus setcc. Revamp ptest instruction. Add test.

Eric Christopher fae639c9ad Move insertps tests to sse41 combo test file, convert to filecheck 
format and add an extract/insert test.

Chris Lattner b9cdd3153c change a test to run in filecheck style. Rename it to be a general 
dumping ground of various SSE4.1 tests, since filecheck can reasonably
handle them all in one file.  Generalize it to check x86-64 stuff as
well since it has a different ABI (a convenient way to test both the 
reg and mem forms of these instructions).
