Alexey Samsonov 8f5138a23f Call __asan_free_hook() before marking the chunk quarantinned
Summary:
With this change, the user may safely call __asan_get_ownership()
from malloc/free hooks and assume it would return "true". If there is a
realloc/free race, free hook might be called twice, but I think it's acceptable,
as it's a data race and would later be reported anyway.

This change also fixes a bug when failing realloc incorrectly marked the
original memory as "quarantinned".

Evgeniy Stepanov 96284becf4 [msan] Handle mixed track-origins and keep-going settings (compiler-rt part).
Before this change, each module defined a weak_odr global __msan_track_origins
with a value of 1 if origin tracking is enabled, 0 if disabled. If there are
modules with different values, any of them may win. If 0 wins, and there is at
least one module with 1, the program will most likely crash.

With this change, __msan_track_origins is only emitted if origin tracking is
on. Then runtime library detects if there is at least one module with origin
tracking, and enables runtime support for it.
