; This testcase checks to see if CodeExtractor properly inherits
;   target specific attributes for the extracted function. This can
;   cause certain instructions that depend on the attributes to not
;   be lowered. Like in this test where we try to 'select' the blendvps
;   intrinsic on x86 that requires the +sse4.1 target feature.
