This patch attempts to reduce the special handling of destructuring assignments in arrow function parameters by "adopting" them from wherever they were initially parsed into the arrow function's FunctionState/Scope. This avoids incorrectly re-setting the Scope of such assignments multiple times for arrow functions that are nested inside other arrow params themselves. It also generally seems better, in that we now only rewrite destructuring assignments for a single function at a time.

When suspending, rather than saving all registers up to a certain index, only save the ones that are live according to the liveness analysis. Others are saved as optimized out constants, and are skipped during the GenaratorStore lowering. Symmetrically, only restore live registers when resuming.

We reuse most of the infrastructure to set break points, with minor differences when we encounter functions where we can only break on entry: - PrepareFunctionForBreakPoints simply deopts all functions. - Break point objects have the canonical source position 0. - Break point is set/checked/cleared via bit on the DebugInfo. - Debug::Break do not continue stepping since stepping is implemented via regular break points and therefore do not interfere with break on entry. I promise to add more tests.

Port 0761b55d Original Commit Message: "Extend the code-generator tests to cover AssembleMove and AssembleSwap with Simd128 registers and stack slots, for targets that support them. For this to work however, we need support for passing Simd128 stack parameters in TurboFan which this patch implements for Arm and x86. PPC and S390 both do not support the Simd128 representation and it appears MIPS and MIPS64's implementation of AssembleMove and AssembleSwap do not support it either. As per the design of the tests, the set of values to perform moves on are represented in a FixedArray of Smis (for kTagged) and HeapNumbers (for kFloat32 and kFloat64). They are converted to raw values for the moves to be performed on, to be then converted back into a FixedArray. For the kSimd128 representation, we represent values as a FixedArray of 4 Smis, each representing a lane. They are converted to a raw Simd128 vector using the `I32x4ReplaceLane` and `I32x4ExtractLane` operations. Finally, these tests need Simd128 variables mixed with the CodeStubAssembler which is not a use-case officially supported. And as a result, the `RecordWrite` stub does not guarantee to preserve Simd128 registers. To get around this, we have to be careful to skip write barriers when dealing with Simd128 parameters inside the "teardown" function, and we've had to move all allocations to the "setup" function. Thanks to this, we are able to catch bugs such as this one https://bugs.chromium.org/p/v8/issues/detail?id=6843."

Cleans up the implementation of trapping/saturating operations to use existing models of types, instead of defining new ones. That is, it uses MachineType to represent the kind of integer/float value the conversion is operating on. It also removes the need to define NumericImplementation by using the actual opcodes to determine if the instruction is trapping or saturating. Finally, it now defines a single method to implement the truncating (that doesn't use a ccall) conversions. The previous code had two methods, one for I32 and one for I64.
