Handle the case when one or both of the output nodes of an I64Atomic op are optimized, for code-gen instructions that use a set of fixed registers, use temp registers to ensure the registers are not clobbered.

Liftoff increases code size, and people start deploying bigger modules. Increase the wasm code space limit from 512 MB to 1024 MB to account for this.

The WasmMemoryTracker keeps track of reserved memory in order to avoid running out of virtual address space. So far, we were only tracking reservations for wasm memory, and not for code. This CL changes that to also include code reservations. Drive-by: Some cleanup around the allocation of the WasmCodeManager.

Indirect calls need a scratch register to load the target address. On ia32 there's no easily-available scratch register. This removes invalid code and documents a potential solution. But ideally, this will remain unreachable since all inter-builtin calls will be pc-relative.

Jakob Gruber authored
In the near future all ia32 ASM builtins must be audited & possibly refactored to ensure they do not address ebx (= kRootRegister). This CL adds mechanisms to verify ebx usage. SupportsRootRegisterScope marks regions that are root-register-ready (i.e. does not use ebx). AllowExplicitEbxAccessScope marks regions that are explicitly allowed to use ebx, e.g. because they spill and restore its value at all boundaries and do not contain any root-relative accesses. Consistency is verified by calling the new AssertIsAddressable function at strategic spots in the Assembler. All of this code is temporary and should be removed once ia32 fully supports the kRootRegister.

If type checks in simplified lowering produced dead value (i.e., of type Type::None()), we have only propagated deadness along value edges. With this CL, we also insert an Unreachable node after every effectful node that produces dead value. This is more consistent with dead code elimination, which also inserts unreachable nodes after effectful nodes with value output None.

Port 0c296cb2 Original Commit Message: This change introduces the necessary conversion operators to convert from Word64 to other representations (Tagged, Word32, Float64, etc.), and plugs in the Word64 representation for NumberAdd/NumberSubtract, such that TurboFan will go to Int64Add/Sub on 64-bit architectures when the inputs and the output of the operation is in safe integer range. This includes the necessary changes to the Deoptimizer to be able to rematerialize Int64 values as Smi/HeapNumber when going back to Ignition later. This change might affect performance, although measurements indicate that there should be no noticable performance impact. The goal is to have TurboFan support Word64 representation to a degree that changing the TypedArray length to an uint64_t (for 64-bit archs) becomes viable and doesn't have any negative performance implications. Independent of that we might get performance improvements in other areas such as for crypto code later.

Port 6346cdb6 Original Commit Message: This adds support to TurboFan's representation selection for the Word64 representation, and makes use of that to handle indices for memory access and allocation instructions (i.e. LoadElement, StoreElement, Allocate, etc.). These instructions had previously used Word32 as representation for the indices / sizes, and then internally converted it to the correct representation (aka Word64 on 64-bit architectures) later on, but that was kind of brittle, and sometimes led to weird generated code. The change thus only adds support to convert integer values in the safe integer range from all kinds of representations to Word64 (on 64-bit architectures). We don't yet handle the opposite direction and none of the representation selection heuristics for the numeric operations were changed so far. This will be done in follow-up CLs. This CL itself is supposed to be neutral wrt. functionality, and only serves as a starting point, and a cleanup for the (weird) implicit Word64 index/size handling.

On Intel platforms, the kX64Cmp32 and kX64Test32 operations in TurboFan's backend automatically truncate their inputs to Word32 (aka they don't look at the upper bits), so the instruction selection can silently ignore TruncateInt64ToInt32 on the inputs.
