Extended Description

For example, on x86-32 gcc reports alignof(double) as 8, whereas the actual alignment is 4.

I think that alignof should map to astcontext preferred alignment.

[efriedma-quic]

I'm going to call this fixed with r65260, since we now get the right result for double on x86.

[llvmbot]

Cool. I'll do another run of my ABITest script, but I think this was the only issue.
