The {movsx_b} instruction can only take byte registers (or operands) as source. Ensure that for i8 sign extensions to i64, the src register is moved to a temporary byte register first, similar to the same operation on i32 a few lines above.

regress-6989 uses assertOptimized and will hence fail randomly depending on GC timing. This means we should not run it under GC stress. This can be verified by running the test under GC stress and changing the --gc-interval. It is easy to find values for which the test fails, and values for which the test passes.

We currently trigger a GC when creating a module while the remaining uncommitted code space is below 32MB. For bigger modules, this is not enough. Instead, make this limit relative: Trigger GC if we fall below 50% of the available code space, and re-adjust this limit after each GC to avoid repeated GCs that do not free anything.

Port f323a5f4 Original Commit Message: Currently, Torque's builtin pointers store a Code target underneath and callsites generate a kArchCallCodeObject opcode. When embedded builtins are enabled, the call thus first calls the on-heap trampoline, which finally jumps to the target off-heap builtin code. This will no longer be possible in jitless mode, since on-heap code must not be executable. As a step towards changing the way builtin pointers are called (function pointers will hold the builtin index as a Smi, and callsites look up the off-heap target address and jump there), this CL adds a dedicated opcode for builtin pointer calls to the compiler pipeline. The calling mechanism itself is unchanged, changes there will happen in a follow-up.

We currently de-duplicate used registers also in regions which do not need merging. In those regions though it can never happen that we need to pass different values from any merge input. Apart from introducing unnecessary register moves, this also causes a DCHECK to fail, because we might later want to merge back different registers into one. Assume this initial stack state (where each letter is a register): [A B B C] If in any child block the two Bs get de-duplicated so something like [A B D C] then we run into trouble when merging back this state into the parent state, because both B and D would need to be put into B. In this case we can statically infer that B and D must hold the same value anyway, but having this situation does not make much sense in the first place, so the DCHECK fires correctly.

On x64 the {kScratchRegister} cannot be held in a {LiftoffRegister}, since it is not a valid cache register. Also, the code unnecessarily checked whether there is an unused cache register, but then didn't use it. Simplify the logic to always use the scratch register, just distinguish between 4-byte and 8-byte moves. On ia32 we did not move 64-bit values correctly if we didn't have unused registers and needed to move via the stack.

Instead of de-sugaring destructuring assignment in the parser (using the pattern rewriter), pass the Object/ArrayLiterals through to the bytecode generator, which can desugar them in-place. This allows us to decrease the amount of AST node creation, and improve the generated bytecode using domain-specific knowledge. As a side effect we partially fix an old execution ordering spec bug. Currently only implemented for assignments, not declarations, as the latter has some additional complexity.

Port a55803a1 Original Commit Message: This change makes the SFI to bytecode link pseudo-weak. The marking visitors check whether the bytecode is old, and if so, don't mark it and instead push the SFI onto a bytecode_flushing_candidates worklist. Once marking is complete, this list is walked, and for any of the candidates who's bytecode has not been marked (i.e., is only referenced by the shared function info), the bytecode is flushed and the SFI has the function data replaced with an UncompiledData (which overwrites the flushed bytecode array). Since we don't track JSFunctions, these can still think the underlying function is compiled, and so calling them will invoke InterpreterEntryTrampoline. As such, logic is added to InterpreterEntryTrampoline to detect flushed functions, and enter CompileLazy instead.
