[Patch,Fortran] -fcheck=bounds fix; intrinsic.texi: INT*/REAL* documentation

[Tobias Burnus]

Dear all,

here are two minor fixes:

-fcheck=bounds did not always works as an if(f_bounds_check) was left;
found while debugging PR 40383.

When writing the gcc-4.5/changes.html, I realized that INT* and REAL*
were not documented.

Build and regtested on x86-64-linux. I intent to commit the patch as
obvious in a couple of hours, unless someone objects.

	* trans-decl.c (gfc_generate_function_code): Use gfc_option.rtcheck
	instead of flag_bounds_check.
	* intrinsic.texi (ISO_FORTRAN_ENV): Document INT{8,16,32,64} and
	REAL{32,64,128}.
