  Changed paths:
    M compiler-rt/lib/hwasan/hwasan_allocator.cpp
    A compiler-rt/test/hwasan/TestCases/short-granule-disabled.cpp

  Log Message:
  -----------
  [hwasan] Always untag short granule in shadow.

Fixes a regression when the allocator is disabled, and a dirty
allocation is re-used. This only occurs when the allocator is disabled,
so a test-only fix, but still necessary.
