  Log Message:
  -----------
  [SelectionDAG][RISCV][AArch64] Allow f16 STRICT_FLDEXP to be promoted. Fix integer promotion of STRICT_FLDEXP in type legalizer. (#117633)

A special case in type legalization wasn't accounting for different
operand numbering between FLDEXP and STRICT_FLDEXP.

AArch64 already asked STRICT_FLDEXP to be promoted, but had no test for
it.
