Evgeniy Stepanov	090f0f9504	[hwasan] Record and display stack history in stack-based reports. Summary: Display a list of recent stack frames (not a stack trace!) when tag-mismatch is detected on a stack address. The implementation uses alignment tricks to get both the address of the history buffer, and the base address of the shadow with a single 8-byte load. See the comment in hwasan_thread_list.h for more details. Developed in collaboration with Kostya Serebryany.

[hwasan] Record and display stack history in stack-based reports.

Summary:
Display a list of recent stack frames (not a stack trace!) when
tag-mismatch is detected on a stack address.

The implementation uses alignment tricks to get both the address of
the history buffer, and the base address of the shadow with a single
8-byte load. See the comment in hwasan_thread_list.h for more
details.

Developed in collaboration with Kostya Serebryany.
