compiler.h: move __is_constexpr() to compiler.h
Prior to f747e6667ebb2 __is_constexpr() was in its only user minmax.h.
That commit moved it to const.h - but that file just defines ULL(x) and
UL(x) so that constants can be defined for .S and .c files.
So apart from the word 'const' it wasn't really a good location. Instead
move the definition to compiler.h just before the similar
is_signed_type() and is_unsigned_type().
This may not be a good long-term home, but the three definitions belong
together.
