[PATCH] D72993: [NFC][Codegen] Use MaybeAlign + APInt::getLimitedValue() when creating Alignment attr

[Roman Lebedev via Phabricator via cfe-commits]

lebedev.ri created this revision.
lebedev.ri added reviewers: erichkeane, gchatelet, courbet, jdoerfert.
lebedev.ri added a project: clang.
lebedev.ri added a parent revision: D72979: [Codegen] Emit both AssumeAlignedAttr and AllocAlignAttr assumptions if they exist.

Just an NFC code cleanup i stumbled upon when stumbling through clang alignment attribute handling.
