Sanjay Patel	e713c47d49	[DAGCombiner] fix crash when converting build vector to shuffle The regression test is reduced from the example shown in D56281. This does raise a question as noted in the test file: do we want to handle this pattern? I don't have a motivating example for that on x86 yet, but it seems like we could have that pattern there too, so we could avoid the back-and-forth using a shuffle. llvm-svn: 351753	2019-01-21 17:30:14 +00:00

of the current outputs (if any) is considered optimal, but
