  Log Message:
  -----------
  Reapply "[AArch64][SVE] Pair SVE fill/spill into LDP/STP with -msve-vector-bits=128." (#135177)

Reapplies #134068.

The first patch was missing a check to prevent attempts to pair SVE
fill/spill with other Neon load/store instructions, which could happen
specifically if the Neon instruction was unscaled.
