llvm-mirror/test/CodeGen/ARM/neon-vmovn.ll
David Green 61eab1d530 [ARM] Fix ReconstructShuffle for bigendian 
Simon pointed out that this function is doing a bitcast, which can be
incorrect for big endian. That makes the lowering of VMOVN in MVE
wrong, but the function is shared between Neon and MVE so both can
be incorrect.

This attempts to fix things by using the newly added VECTOR_REG_CAST
instead of the BITCAST. As it may now be used on Neon, I've added the
relevant patterns for it there too. I've also added a quick dag combine
for it to remove them where possible.
