History
Ahmed Bougacha c52cd839b9 [AArch64] Improve codegen of store lane 0 instructions by directly storing the subregister. 
For 0-lane stores, we used to generate code similar to:

  fmov w8, s0
  str w8, [x0, x1, lsl #2]

instead of:

  str s0, [x0, x1, lsl #2]

To correct that: for store lane 0 patterns, directly match to STR <subreg>0.

Byte-sized instructions don't have the special case for a 0 index,
because FPR8s are defined to have untyped content.
