983eec8979 [destructuring] Various cleanup and simplification in PatternRewriter
This patch simplifies and reduces code duplication & dead branches
in PatternRewriter, especially relating to handling of destructuring
assignments. It also adds additional DCHECKs to capture invariants.

It should have no change in behavior.

b0d09b4967 [arm64] Fix Simd128 register moves and swaps.
FPRegister <-> FPRegister moves and swaps were implemented using the FMOV
instruction, whatever the size of the register. However, FMOV only supports
Float and Double moves, it cannot move a whole 128bit register.

Instead, use the vector MOV instruction:

- Simd128 move:      mov vd.16b, vn.16b
- Float/Double move: mov vd.8b, vn.8b

24a19a4353 [arm] Fix Float32 constant to Float slot move.
The code generator uses `ip` as a scratch register directly to assemble a
"Constant -> Float stack slot" move. However, the assembler may also use it to
compute the address.

If we try to assemble such a move and the stack slot is out of range of a store
we get the following:
~~~
movw ip, #52429
movt ip, #15820
movw ip, #59328   ; Use ip to compute the address!
movt ip, #65535
str ip, [fp, +ip]
~~~

With awaitPromise flag Runtime.evaluate awaits
Promise.resolve(<expression result>).
This also allows to await for any non-Promise value, similar to await
expression, which is more convenient for most protocol users.

4b397e6c90 [wasm] Reuse reloc info size and address accessors.
The way we access wasm addresses or sizes is the same, on
a platform. We have 2 size parameters - memory and table - and
2 addresses - globals and memory.

The CL also renames for generality the address setting API.

4c503b65d9 Throw a WasmErrorObject rather than an integer.
Fixes the implementation of wasm exceptions to use a WasmRuntimeError
object, and set the exception tag value as a property of the
object. This guarantees that an uncaught wasm exception is treated
like all other runtime errors.

22611e8e84 PPC/s390: [Interpreter] Remove new.target from fixed frame slot.
Port c820b89bc5

Original Commit Message:

    Removes the new.target slot from the interpreter's fixed frame. Instead
    adds a field to BytecodeArray to get the bytecode's incoming
    new.target or generator object register. The InterpreterEntryTrampoline
    then sets this register with the incoming new.target (or generator object)
    when the function is called. This register can be directly the new.target
    or generator object variable if they are LOCAL location, otherwise it is a
    temporary register which is then moved to the variable's location during the
    function prologue.

    This fixes a hack in the deoptimizer where we would set the new.target fixed
    slot to undefined in order to avoid extending it's lifetime through the
    optimized code - now it's just a standard register and can be optimized away
    as normal.

06d91dacc0 [Compiler] Split CompileUnoptimizedCode into main and non-main thread phases
Splits CompileUnoptimizedCode into a non-main thread GenerateUnoptimizedCode and
a main thread FinalizeUnoptimizedCode phase. Adds Disallow<HeapAccess> scopes in
CompileUnoptimizedCode to ensure no access to the heap during this phase.

Also cleans up a few heap accesses in CompilationInfo's constructor to avoid
violating the disallowed heap access.

Currently we reallow heap access during asm.js compilation as a temporary
measure until the script streamer uses an off-heap script buffer.

19ae2fc1af [heap] Refactor object marking state (part 2).
This follows up 4af9cfcc by separating incremental marking state
from the full MC marking state. Runtime and tests now use only
the incremental marking state. The full MC marking state used
by MC during atomic pause.

This separation decouples atomicity of markbit accesses
during incremental marking and during full MC.
