[PATCH] ppc: testsuite: vec-mul requires vsx runtime

[Alexandre Oliva <oliva@adacore.com>]

vec-mul is an execution test, but it only requires a powerpc_vsx_ok
effective target, which is enough only for compile tests.  In order to
To check for runtime and execution environment support, we need to
require vsx_hw.  Make that a condition for execution, but still
perform a compile test if the condition is not satisfied.

Regstrapped on ppc64le-linux-gnu, also tested on
x86_64-linux-gnu-x-ppc-vx7r2 (no vsx execution support)
Ok to install?  gcc-12?  gcc-11?


for  gcc/testsuite/ChangeLog

	* testsuite/powerpc/vec-mul.c: Run on target vsx_hw, just
	compile otherwise.
