  -----------
  [llvm][AArch64][SVE] Fold literals into math instructions

SVE has predicated literal forms of some instructions for specific
literals, which currently are generated correctly when using ACLE
but not when those instructions are generated directly.

This adds the patterns to generate those instructions when
generating from standard LLVM IR instructions.
