Subject: CpuProfiler: log pc offset for deopts.
X-Git-Tag: upstream/4.7.83~3782
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7fef610d723b09f51573a58ae8c89ed15069488a;p=platform%2Fupstream%2Fv8.git

CpuProfiler: log pc offset for deopts.

This is the fifth part of https://codereview.chromium.org/1012633002
In this part we collect the offsets of deopt calls and save it into
an inlined function info.

On the Next:
Later when deopt happens we will get the offset of deopt call and
search it among inlined infos.

BUG=chromium:452067
LOG=n
