Reason for revert: Performance regressions in Gameboy, Life, CodeLoad and others. See crbug.com/638210. Original issue's description: > Refactor data structures for simple stack traces > > Simple stack traces are captured through Isolate::CaptureSimpleStackTrace. > Captured frames are stored in a FixedArray, which in turn is stored as a > property (using a private symbol) on the error object itself. Actual formatting > of the textual stack trace is done lazily when the user reads the stack > property of the error object. > > This would involve many conversions back and forth between index-encoded raw > data (receiver, function, offset and code), JS CallSite objects, and C++ > CallSite objects. > > This commit refactors the C++ CallSite class into a Struct class called > StackTraceFrame, which is the new single point of truth frame information. > Isolate::CaptureSimpleStackTrace stores an array of StackTraceFrames, and JS > CallSite objects (now created only when the user specifies custom stack trace > formatting through Error.prepareStackTrace) internally only store a reference > to a StackTraceFrame. > > BUG= > > Committed: https://crrev.com/b4c1aefb9c369f1a33a6ca94a5de9b06ea4bf5c4 > Cr-Commit-Position: refs/heads/master@{#38645} TBR=yangguo@chromium.org # Not skipping CQ checks because original CL landed more than 1 days ago.
