The difference to Chromium is that we support frame pointers and thus integrate better with debugging in e.g. gdb.

From recent discussions on https://crrev.com/c/2057355 it became clear that the FixedRawData serializer bytecodes need to be refactored. This CL - updates documentation to correctly specify that data length is given in kTaggedSize unit, and - changes the way smi roots are serialized s.t. deserialization no longer needs hacks to be correct on big-endian architectures and when (theoretically) deserializing sequences of smi roots. We do this by serializing the full object slot for smi roots instead of just the smi contents.

For keyed stores we recompute handlers based on the receiver maps we have seen. This is done so that we can transition to the most generic elements kind we have seen so far. When we recompute this handlers we get a new prototype validity cell and ignore the existing cell. This leads to incorrect behaviour if the cell was invalid. Recomputing the handler may be extra work which is not worth doing at this point. So we just reuse the existing validity cell and let the IC recompute the handler if we see the map again.

This reverts commit 8f68e392. Reason for revert: depot_tools started using Python3 by default with this deps roll, but it contained a Python3 bug.

Use inline asm to generate the x64 PushAllRegistersAndIterateStack which is the trampoline for conservative stack scanning. Keep the function definition as C code to allow clang to generate the correct mangling for each platform. This approach has the benefit that it immediately works for all platforms that support clang.

The trampoline should never inline the actual iteration method and always use a full call. As a result, there can be no interesting data in the redzone. This allows simplifying as the existence and size of a red zone is platform dependent.

Double literals without dots should still be parsed as double constants, not unsigned constants. The static_cast would remove the fractional part, making constants like "1e-15" come out as "0" unsigned constants. The precise semantics is not spec'ed, so we still consider literals like "1e1" to be unsigned, and only switch to double if there is a fractional part.

Port a447a44f https://crrev.com/c/2064226 Original Commit Message: Since now the IterationBody StackChecks are implicit within JumpLoops, we are able to eagerly deopt in them. If we do that, whenever we advance to the next bytecode we don't have to advance to the next literal bytecode, but instead "advance" in the sense of doing the JumpLoop. Adding tests that test this advancing for wide and extra wide JumpLoops. Also, marking JumpLoop as needing source positions since now it has the ability of causing an interrupt.

This makes many template instantiations much shorter and hence easier to read. Drive-by: Replace break after function by return.

Liftoff has lots of macros that just convert between {LiftoffRegister} and either {Register} or {DoubleRegister}. This CL avoids most of these lambdas by passing the original assembler function to {EmitUnOp} and {EmitBinOp}, and converting the register types only when calling the respective function. This makes the code in many macros a lot shorter, and might allow us to eliminate many macros and just inline their code.
