Here's a Holiday present for Fortranners.

2018-12-25  Steven G. Kargl  <kargl@gcc.gnu.org>

	* cpp.c (gfc_cpp_init):  Add pre-defined macros for INTEGER(1)
	INTEGER(2), INTEGER(8) and INTEGER(16) if supported.  Add pre-defined
	macros for REAL(10) and REAL(16) if available.
	* gfortran.texi: Document new macros.

As a Fortran compiler is required to have default integer kind, 
default real kind, and double precision, I did not include macros
for these types (ie., there are no __GFC_INTEGER_4__, __GFC_REAL_4__,
and __GFC_REAL_8__).

This allows code like

% cat a.F90
program foo
#ifdef __GFC_REAL_16__
   real(16) x
   x = 1
   print *, x
#endif
end program foo
%  gfcx -o z a.F90 && ./z
   1.00000000000000000000000000000000000

yes, that's suppose to be 16.
