  Log Message:
  -----------
  [hwasan] Add default "/" prefix.

Add a default "/" prefix to the symbol search path in the
symbolization script. Without this, the binary itself is not considered
a valid source of symbol info.

  Changed paths:
    M compiler-rt/test/hwasan/TestCases/thread-uaf.c

  Log Message:
  -----------
  [hwasan] Fix TestCases/thread-uaf.c.

On newer glibc, this test detects an extra match somewhere under
pthread_getattr_np. This results in Thread: lines getting spread out in
the report and failing to match the CHECKs.

Fix the CHECKs to allow this possibility.

  Log Message:
  -----------
  [scudo] Fix running tests under hwasan.

When built with hwasan, assume that the target architecture does not
support TBI. HWASan uses that byte for its own purpose, and changing it
breaks things.
