[PATCH] D54604: Automatic variable initialization

[JF Bastien via Phabricator via cfe-commits]

jfb updated this revision to Diff 177600.
jfb added a comment.

- Make sure uninit-variables.c doesn't break.
- Address Peter's comments, improve tests.
- Add an ugly option to enable zero init
- Update warning-flags.c
- Fix typo
- Use negative NaN with repeated 0xFF payload for all floating-point types. This is potentially faster to initialize than pure positive no-payload NaNs.
