Kostya Serebryany daa1bf3b74 [asan] rewrite asan's stack frame layout ... Summary: Rewrite asan's stack frame layout. First, most of the stack layout logic is moved into a separte file to make it more testable and (potentially) useful for other projects. Second, make the frames more compact by using adaptive redzones (smaller for small objects, larger for large objects). Third, try to minimized gaps due to large alignments (this is hypothetical since today we don't see many stack vars aligned by more than 32). The frames indeed become more compact, but I'll still need to run more benchmarks before committing, but I am sking for review now to get early feedback. This change will be accompanied by a trivial change in compiler-rt tests to match the new frame sizes.
