Nate Begeman 265363061e Add the minimal amount of smarts necessary to instcombine of shufflevectors to recognize ... patterns generated by clang for transpose of a matrix in generic vectors. This is made of two parts: 1) Propagating vector extracts of hi/lo half into their users 2) Recognizing an insertion of even elements followed by the odd elements as an unpack. Testcase to come, but this shrinks the # of shuffle instructions generated on x86 from ~40 to the minimal 8. llvm-svn: 110734		2010-08-10 21:38:12 +00:00
