[PATCH] testsuite: Disable zero-scratch-regs-{7, 9, 11}.c on arm

[PATCH] testsuite: Disable zero-scratch-regs-{7, 9, 11}.c on arm

[Torbjörn SVENSSON]

-fzero-call-used-regs=all and -fzero-call-used-regs=all-gpr are not
supported on arm*. On arm-none-eabi, the testcases fails with:

  sorry, unimplemented: '-fzero-call-used-regs' not supported on this target

gcc/testsuite/ChangeLog:

	* c-c++-common/zero-scratch-regs-7.c: Skip on arm.
	* c-c++-common/zero-scratch-regs-9.c: Likewise.
	* c-c++-common/zero-scratch-regs-11.c: Likewise.

[Torbjorn SVENSSON]

Hi all,

Appears that this is just a problem for gcc11 (and perhaps gcc12?). 
Master already has the needed implementation, so the patch below is not 
needed.

Sorry for the buzz.

Kind regards,
Torbjörn
