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.

Import the most commonly used ValueType kinds as constants into {LiftoffCompiler}, so that we don't need the fully-qualified accessor on {ValueType}. This makes many template instantiations much shorter and hence easier to read. Drive-by: Replace break after function by return. This often saves another line, making macros and switch statements much shorter.

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.
