Improve sorry message for -fzero-call-used-regs
When the -fzero-call-used-regs command line option is used with an
unsupported value, indicate that it's a value problem instead of an
option problem.
Without the patch, the error is:
In file included from gcc/testsuite/c-c++-common/zero-scratch-regs-8.c:5:
gcc/testsuite/c-c++-common/zero-scratch-regs-1.c: In function 'foo':
gcc/testsuite/c-c++-common/zero-scratch-regs-1.c:10:1: sorry, unimplemented: '-fzero-call-used-regs' not supported on this target
10 | }
| ^
With the patch, the error would be like this:
In file included from gcc/testsuite/c-c++-common/zero-scratch-regs-8.c:5:
gcc/testsuite/c-c++-common/zero-scratch-regs-1.c: In function 'foo':
gcc/testsuite/c-c++-common/zero-scratch-regs-1.c:10:1: sorry, unimplemented: argument 'all-arg' is not supported for '-fzero-call-used-regs' on this target
10 | }
| ^
