[PATCH] D32070: Object: Shrink the size of irsymtab::Symbol by a word. NFCI.

[Peter Collingbourne via Phabricator via llvm-commits]

pcc created this revision.

Instead of storing an UncommonIndex on the Symbol, use a flag bit to store
whether the Symbol has an Uncommon. This shrinks Chromium's .bc files (after
https://reviews.llvm.org/D32061) by about 1%.
