[PATCH] [AArch64 NEON] Get instruction BSL be matched to VSELECT.

[Tim Northover]

  Hi Kevin,

  From the change, it looks like Neon_bsl may not be needed at all: it appears to have identical semantics to vselect. If so, we should change ISelLowering to produce vselect instead and only have the one pattern.

  Cheers.

  Tim.
