fortran: Expand ieee_arithmetic module's ieee_class inline [PR106579]
The following patch expands IEEE_CLASS inline in the FE but only for the
powerpc64le-linux IEEE quad real(kind=16), using the __builtin_fpclassify
builtin and explicit check of the MSB mantissa bit in place of missing
__builtin_signbit builtin.
