s390: Fix bootstrap error with checking and -m31.
For a while already we hit an ICE when bootstrapping with -m31 and
--enable-checking=all.
../../../../libgfortran/ieee/ieee_helper.c: In function 'ieee_class_helper_16':
../../../../libgfortran/ieee/ieee_helper.c:77:3: internal compiler error: RTL check: expected code 'reg', have 'subreg' in rhs_regno, at rtl.h:1932
77 | }
| ^
../../../../libgfortran/ieee/ieee_helper.c:87:1: note: in expansion of macro 'CLASSMACRO'
87 | CLASSMACRO(16)
| ^~~~~~~~~~
This patch fixes the problem by first checking for reload_completed
and also ensuring that REGNO is only called on reg operands rather
than subregs.
gcc/ChangeLog:
* config/s390/s390.md: Move reload_completed and check operands for REG_P.
