[Codegen] Emit both AssumeAlignedAttr and AllocAlignAttr assumptions if they exist

Authored by lebedev.ri on Jan 18 2020, 10:10 AM.



We shouldn't be just giving up if we find one of them
(like we currently do with AssumeAlignedAttr),
we should emit them all.

As the tests show, even if we materialized good knowledge
from __attribute__((assume_aligned(32), it doesn't mean
__attribute__((alloc_align([...]))) info won't be useful.
It might be, but that isn't given.
