minmax: deduplicate __unconst_integer_typeof()

minmax: deduplicate __unconst_integer_typeof()

commit 5e57418a2031cd5e1863efdf3d7447a16a368172 upstream.

It appears that compiler_types.h already have an implementation of the
__unconst_integer_typeof() called __unqual_scalar_typeof().  Use it
instead of the copy.
