Reland "GWP-ASan: Pack stack traces to save space"
This is a reland of a692ce8d, I forgot to update a length test from kMaxStackFrames to kMaxPackedTraceLength in the original change. Original change's description: > GWP-ASan: Pack stack traces to save space > > Make use of the stack trace packing from https://crrev.com/627865 to > reduce memory usage to store stacks on 64-bit systems by ~60% percent. A > GWP-ASan microbenchmark did not show this change to noticably regress > performance. > > Bug: 896019, 921237 > Change-Id: Iad6e803f18ff12e5fd3079b9821d11bc0918bead > Reviewed-on: https://chromium-review.googlesource.com/c/1448522 > Auto-Submit: Vlad Tsyrklevich <vtsyrklevich@chromium.org> > Commit-Queue: Vitaly Buka <vitalybuka@chromium.org> > Reviewed-by: Vitaly Buka <vitalybuka@chromium.org> > Cr-Commit-Position: refs/heads/master@{#628034} Bug: 896019, 921237, 927488 Change-Id: I3160735a22e197b18911874e3667504f759552ee Reviewed-on: https://chromium-review.googlesource.com/c/1449105Reviewed-by:Vitaly Buka <vitalybuka@chromium.org> Commit-Queue: Vlad Tsyrklevich <vtsyrklevich@chromium.org> Cr-Commit-Position: refs/heads/master@{#628260}
