Re-apply 40504, but with a fix for the segfault it caused in oggenc:
...
Make the alignedload and alignedstore patterns always require 16-byte
alignment. This way when they are used in the "Fs" instructions, in which
a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.

As the number of parameter attributes increases,
...
Verifier::visitFunction is suffering a combinatorial
explosion due to the number of mutually incompatible
attributes. This patch tidies the whole thing up
using attribute masks. While there I fixed some
small bugs: (1) the ByVal attribute tests cast a
type to a pointer type, which can fail. Yes, the
fact it is of a pointer type is checked before,
but a failing check does not cause the program
to exit, it continues on outputting further errors;
(2) Nothing was checking that an sret attribute is
on the first parameter; (3) nothing was checking that
a function for which isStructReturn() is true has a
parameter with the sret attribute and vice-versa (I
don't think it is possible for this to go wrong, but
it seems right to check it).
