[PATCH] D11407: [ARM] - Fix lowering of shufflevectors in AArch32

[Luke Cheeseman]

LukeCheeseman updated this revision to Diff 30507.
LukeCheeseman added a comment.

Adding more tests to check lowering of more shufflemask patterns. Also, slight change to how WhichResult is set, if the first element of the shufflemask was undef then it would incorrectly set WhichResult to 1 when it should be 0 (in the double length shufflemask case)
