Hi Ahmed,
A quick note: I think this is going to fail in the presence of the target
attribute. I.e. if someone decorates a function with
__attribute__((target("avx512"))) this is unlikely to catch that.
Also, should we do this for all of the x86 OSes?

Log:
[X86] Conditionalize Darwin MaxVectorAlign on the presence of AVX.
There's no point in using a larger alignment if we have no instructions
that would benefit from it.
