[PATCH] PR fortran/91959 -- Re-arrange matching of %FILL

[Steve Kargl]

The attached patch has been tested on x86_64-*-freebsd.
OK to commit.

Apparently, DEC Fortran allows one to use %FILL as a variable name.
When the -fdec code was added to gfortran, variable_decl was updated
to match %FILL.  This was done by first ilooking for the % character,
and if found, it is burned and FILL is then match.  Unfortunately,
as the new testcase shows this allowed any variable starting with
% to match.  The patch re-arranges the code so that an error is
issues for variables starting with %, which are not %FILL.
