0113e4e3f2 Fix PR8828 by removing the explicit def in MovePCToLR as well as the pointless 
piclabel operand. The operand in the tablegen definition doesn't actually turn
into an MI operand, so it just confuses anything checking the TargetInstrDesc
for the number of operands. It suffices to just have an implicit def of LR.

2a8eb722c7 In r131488 I misunderstood how VREV works. It splits the vector in half and splits each half. Therefore, the real problem was that we were using a VREV64 for a 4xi16, when we should have been using a VREV32. 
Updated test case and reverted change to the PerfectShuffle Table.

c81c9709ef vrev is incorrectly defined in the perfect shuffle table. The ordering is backwards (should be 0x3210 versus 0x1032) which exposed a bug when doing a shuffle on a 4xi16. I've attached a test case.
