[PATCH] D53227: [hwasan] add stack frame descriptions.

[Kostya Serebryany via Phabricator via llvm-commits]

kcc created this revision.
kcc added reviewers: morehouse, eugenis.
Herald added subscribers: kubamracek, srhines.

At compile-time, create an array of {PC,HumanReadableStackFrameDescription}
for every function that has an instrumented frame, and pass this array
to the run-time at the module-init time.
Similar to how we handle pc-table in SanitizerCoverage.
The run-time is dummy, will add the actual logic in later commits.
