Subject: [turbofan] Fix overzealous reserving of lazy deopt space.
X-Git-Tag: upstream/4.7.83~1971
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d4a74f08d29684ba50362fb78c5a716b1f44e6cb;p=platform%2Fupstream%2Fv8.git

[turbofan] Fix overzealous reserving of lazy deopt space.

This fixes CodeGenerator::EnsureSpaceForLazyDeopt to no longer be
treated as a lazy deopt site in itself. Calls mark themselves as lazy
bailout sites in CodeGenerator::RecordCallPosition, which suffices.
