PGI-Fortran: Add -Mipa=fast,inline as IPO option.
Remove -Mipa=fast as a default flag and add it as an option instead.
-Mipa=fast is a flag that speeds up runtime but at the cost of significant
compile time increase and therefore, shouldn't be a default flag.
In addition, -Mipa isn't supported on PGI OpenPOWER or x86/llvm compilers.
