Log:
PR target/79890: S/390: Fix crash.

builtin_eh_return requires the return address to be saved on the
stack.  The patch prevents using an FPR for that.

Reproduceable on a zEC12 with

 $ ./configure --enable-languages=c --disable-bootstrap --disable-multilib
--enable-checking --with-system-zlib --enable-threads=posix
--enable-__cxa_atexit --enable-gnu-indirect-function

I see the ICE with cross-compiler (on x86_64-linux-gnu), compiled with
--target=s390x-linux-gnu.

Not reproduceable here with r245913.  Is it gone with a recent Gcc?

Gcc configured with --with-arch=zEC12 and compiled without explicit options:

$ ~/src/gcc/install-master/bin/gcc
~/src/gcc/gcc/testsuite/gcc.target/mips/call-saved-7.c -march=zEC12 -S

(Complains about missing main function without "-S")

I do some basic fuzzing. This test-case just uses builtins, thus I consider it
generic enough to report it.

The ICE needs to be fixed, of course, by what is the idea behind executing the
mips testsuite on s390?
