Eli Friedman 34505083c6 Don't combine a shuffle of two BUILD_VECTORs with duplicate elements. ... Targets can't handle this case well in general; we often transform a shuffle of two cheap BUILD_VECTORs to element-by-element insertion, which is very inefficient. Fixes https://llvm.org/bugs/show_bug.cgi?id=31364 . Partially fixes https://llvm.org/bugs/show_bug.cgi?id=31301.
