This removes the obsolete {Crankshaft} factory method as it returns the same configuration as the {Turbofan} factory by now. We now consistently use {RegisterConfiguration::Default} everywhere.

This begins splitting up the Deserializer class into {Object,Partial,Startup}Deserializer. For now, all functionality remains in the Deserializer base clase, to be refactored in future CLs.

Previously TryToName bailed out for Oddball keys (i.e. when passing true or false as the key), which meant that for example the generic KeyedLoadIC would always bail out to the %KeyedGetProperty runtime function. But handling Oddball keys is fairly easy, since every oddball value carries it's unique string representation. Adding just this case to the CodeStubAssembler::TryToName method boosts this simple micro-benchmark by a factor of 4x: const n = 1e7; const obj = {}; const key = true; console.time('foo'); for (let i = 0; i < n; ++i) { if (obj[key] === undefined) { obj[key] = key; } } console.timeEnd('foo'); It also shows on the ARES-6 ML benchmark and on several Speedometer tests, where objects are being used as dictionaries and the developers rely on the implicit ToString conversions on the property accesses. In the ARES-6 ML benchmark, the number of calls to %KeyedGetProperty is reduced by 137,758.

Port 895c3219 Original Commit Message: Replacing pc with trampoline on stack This CL is the follow up of https://chromium-review.googlesource.com/c/586707/ which used to crash when running the gc-stress bots. It seems to be working now. We now keep the trampoline PC in the Safepoint table and use that information to find SafepointEntries. There's some refactoring that can be done, such as changing the code for exceptions in a similar way and removing the trampoline from the DeoptimizationInputData. Will take care of this in the next CL.

My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js. There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs. Drive by: debugger-script.js and usage of debugger context in inspector code base.

This CL does the first baby steps on moving the current (experimental) exception handling to match that of the WebAssembly proposal. It does the following: 1) Use exception tags instead of integers. 2) Only handle empty exception signatures (i.e. no values associated with the exception tag. 3) Only handle one catch clause. 4) Be sure to rethrow the exception if the exception tag does not match. Note: There are many things that need to be fixed, and are too numerous to list here. However, the code should have TODO's on each missing parts of the implementation. Also note that the code currently doesn't handle nested catch blocks, nor does it change the throw value being an integer. Rather, the integer value is still being thrown, and currently is the exception tag. Therefore, we don't build an exception object. This is the reason why this CL doesn't handle exceptions that pass values. Also, the current implementation still can't handle multiple modules because tag resolution (between) modules has not be implemented yet.

Some bailout reasons are never referenced. Removing these allows us to decrease the size of bailout reason bit-fields to 7 bits.

This fixes a corner case of rewriting the transition trees, where the "interesting symbols" bit was not properly forwarded. Drive-by-fix: Introduce additional checking in Map::ConnectTransition to make it easier for clusterfuzz to detect cases we might have missed.

This CL adds a DCHECK to make the uses() function safer: we store what the next pointer should be to comparing with the next use (from the current element in the linked list). This helps detect code which invalidates the use-list iterator, which would otherwise cause hard-to-debug errors.
