Nate Begeman	624690c6b2	Adapt the x86 build_vector dagcombine to the current state of the legalizer. ... build vectors with i64 elements will only appear on 32b x86 before legalize. Since vector widening occurs during legalize, and produces i64 build_vector elements, the dag combiner is never run on these before legalize splits them into 32b elements. Teach the build_vector dag combine in x86 back end to recognize consecutive loads producing the low part of the vector. Convert the two uses of TLI's consecutive load recognizer to pass LoadSDNodes since that was required implicitly. Add a testcase for the transform.

Mon P Wang	523c0852c6	Fix a problem with DAGCombine where we were building an illegal build ... vector shuffle mask. Forced the mask to be built using i32. Note: this will be irrelevant once vector_shuffle no longer takes a build vector for the shuffle mask. llvm-svn: 67076	2009-03-17 06:33:10 +00:00
