  Log Message:
  -----------
  [X86] X86FixupVectorConstants - split ConvertToBroadcastAVX512 helper to handle single bitwidth at a time.

Attempt 32-bit broadcasts first, and then fallback to 64-bit broadcasts on failure.

We lose an explicit assertion for matching operand numbers but X86InstrFoldTables already does something similar.

Pulled out of WIP patch #73509
