[PATCH] D61698: [COFF] Store alignment in log2 form, NFC

[Reid Kleckner via Phabricator via llvm-commits]

rnk created this revision.
rnk added reviewers: ruiu, aganea.
Herald added a project: LLVM.

Valid section or chunk alignments are powers of 2 in the range [1,
8192]. These can be stored more canonically in log2 form to free up some
bits in Chunk. Combined with D61696 <https://reviews.llvm.org/D61696>, SectionChunk gets 8 bytes smaller.
