Reland "[compiler] Do MapRef::CanBeDeprecated and ::CanTransition concurrently"
This is a reland of abe4858b Reason: It was speculatively reverted but it doesn't seem to have been the culprit. TBR=neis@chromium.org Original change's description: > [compiler] Do MapRef::CanBeDeprecated and ::CanTransition concurrently > > CanBeDeprecated looks at the DescriptorArray, and CanTransition at the > instance_type. Both are safe to read concurrently and we just had to > enable them with the macro. > > Bug: v8:7790 > Change-Id: Iafe6470f2d64a9ed38383cb9e4d00dd6f23d05d7 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2826539 > Reviewed-by: Georg Neis <neis@chromium.org> > Commit-Queue: Santiago Aboy Solanes <solanes@chromium.org> > Cr-Commit-Position: refs/heads/master@{#73995} Bug: v8:7790 Change-Id: I51d29d53b208fe9b6b27adc46561a4e1009e8d6f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2831488Reviewed-by: Santiago Aboy Solanes <solanes@chromium.org> Commit-Queue: Santiago Aboy Solanes <solanes@chromium.org> Cr-Commit-Position: refs/heads/master@{#74007}
