  [RISCV][GISel] Support f32/f64 powi. (#117937)

Need to force libcall legalization to treat the integer argument as
signed so that it can be promoted to XLen in call lowering for RV64.
Alternatively we could promote the operand before converting to libcall,
but going through call lowering is closer to what SelectionDAG does.
