  Log Message:
  -----------
  [flang] Lower exponentiation without using pgmath.

Exponentiation is lowered to either math::FPowI or Fortran runtime
call (in case of --math-runtime=precise).

MathToFuncs convertor will convert math::FPowI operations with
exponent width >32 to calls of outlined implementations and otherwise
will leave the operation to MathToLLVM convertor.
