[PATCH] D106701: [clang] Add -falign-loops=N where N is a power of 2

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

Ping.

- -falign-loops= is currently silently ignored.
- -fliang-loops= has user interest from at least x86 and RISC-V.
- This patch makes it work for the non-LTO case.

I think this is good enough.

The LTO case require a function attribute (this doesn't apply to synthesized functions)/module flags metadata which may be overkill.
