[Patch, fortran] PR30081 - Failure to overload non-generic intrinsics

[Paul Thomas]

:ADDPATCH fortran:

This problem seemed very mysterious, at first, but turns out to be 
rather simple.  If resolve_generic_f/s fail to find a module procedure 
whos interface matches the actual, they turn to intrinsics to see if a 
match can be found.  This was done by searching amongst the generic 
intrinsics.  However, this is unnecessarily restrictive since the 
standard permits non-generic intrinsics to be overloaded.  The fix was 
implemented by substituting gfc_generic intrinsic by 
gfc_intrinsic_name.  The testcase is the contributors.

Regtested on Cygwin_NT/amd64 - OK for trunk and 4.2?
