[PATCH] D110747: [NFC] Restore magic and magicu to a globally visible location

[Christopher Tetreault via Phabricator via llvm-commits]

ctetreau added a comment.

I decided to create a new file in llvm/Support rather than take one of the suggestions in Chris's diff thread because:

- MathExtras.h - I didn't want to add a #include to APInt.h where there wasn't one already. Plus, that file is already pretty big, and most users of it don't need this.
- somewhere in lib/CodeGen - our usage in my downstream is in lib/Target, which I think demonstrates that this functionality is more broadly useful.

Given this, I think a new file in lib/Support is appropriate.
