rs6000: Fix -mpower9-vector -mno-altivec ICE (PR87560)
PR87560 reports an ICE when a test case is compiled with -mpower9-vector
and -mno-altivec. This patch terminates compilation with an error when
this combination (and other unreasonable ones) are requested.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu with no
regressions. Reported error is now:
f951: Error: '-mno-altivec' turns off '-mpower9-vector'
