[PATCH] Fix PR 65109 - [5 Regression] r220674 causes FAIL: gcc.target/powerpc/ppc64-abi-1.c execution test

[David Edelsohn]

The patch below tweaks the ppc64-abi-1.c test to make it less
prone to volatile registers getting clobbered before the test
has had a chance to save them for later comparison to their
expected values.  This resolves the test failure discussed
in PR 65109.

PR target/65109
* gcc.target/powerpc/ppc64-abi-1.c: Split test functions into
 two parts.  One to save registers, the other to verify the
registers have the right values.  Save register state into
static data rather than on the stack.

Okay.

Thanks, David
