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".

[lsan] Add __lsan_disable() and __lsan_enable().

Objects allocated after a call to __lsan_disable() will be treated as
live memory. Also add a ScopedDisabler.

[ASan] Do not buffer stdin in asan_symbolize.py

git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@183006 91177308-0d34-0410-b5e6-96231b3b80d8

[lsan] Added a dummy unittest to suppress LIT warnings.

git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@183004 91177308-0d34-0410-b5e6-96231b3b80d8

[lsan] Run the leak detection tests under both ASan and LSan.

Change the LSan lit test logic. Now "check-lsan" tests the leak
checking functionality in both standalone LSan and ASan.

[msan] Fix gcc build of msan runtime.

git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@182999 91177308-0d34-0410-b5e6-96231b3b80d8

[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.

Add compile time tests for sizes and offsets of all sanitizer-posix types.

git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@182993 91177308-0d34-0410-b5e6-96231b3b80d8

[ASan] Minor cleanup: remove a couple of unused variables.

git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@182915 91177308-0d34-0410-b5e6-96231b3b80d8

[asan] Fix r182858.

[asan] Make ASan report the correct thread address ranges to LSan.

This CL enables thread support in LSan when used on top of ASan.

git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@182854 91177308-0d34-0410-b5e6-96231b3b80d8

[sanitizer] Change the way GetThreadStackAndTls() obtains the thread descriptor address.

Instead of using arch_prctl(ARCH_GET_FS), read the address from the
tread descriptor itself. This lets us avoid sandboxing issues. Also,
GetThreadStackAndTls() can now be implemented on i386.
