[Fortran] Use MIN/MAX_EXPR or IFN_FMIN/MAX for min/max intrinsics when possible

* trans-intrinsic.c: (gfc_conv_intrinsic_minmax): Emit MIN_MAX_EXPR
or IFN_FMIN/FMAX sequence to calculate the min/max when possible.

* gfortran.dg/max_fmax_aarch64.f90: New test.
* gfortran.dg/min_fmin_aarch64.f90: Likewise.
* gfortran.dg/minmax_integer.f90: Likewise.
