[PATCH] D37860: [MSan] Enable use-after-dtor instrumentation by default.

[Matt Morehouse via Phabricator via llvm-commits]

morehouse created this revision.

Enable the compile-time flag -fsanitize-memory-use-after-dtor by
default. Note that the run-time option MSAN_OPTIONS=poison_in_dtor=1
still needs to be enabled for destructors to be poisoned.
