should use its own copy of the u_cpu bits). The
fiddling we do in lp_bld_init() wrt SSE (LP_FORCE_SSE2 and also avx
disabling) isn't a clean way neither.
So this looks like as good a solution as others.

Previously gallivm would attempt to use VSX instructions on all systems
where it detected that Altivec is supported; however, VSX was added to
POWER long after Altivec, causing lots of crashes on older POWER/PPC
hardware, e.g. PPC Macs. By detecting VSX separately from Altivec we
disable it on hardware that supports Altivec but not VSX
