[LLVMdev] Bootstrapping Clang with MemorySanitizer

[Evgeniy Stepanov]

Hi all,

MemorySanitizer (-fsanitize=memory flag) can now be used to build a
self-hosted Clang. Several tests are still failing (most - due to bugs
in the code), but the third-stage compiler is fully functional and
passes the full test suite.

Instructions are here:
