This flag enables the CPU profiler before running any scripts in D8. This is so that we can turn the flag on during fuzzing to help us find security and stability issues. Right now this flag has problems with a bunch of tests under mjsunit/asm which fail in the stack walker when the flag is on. I'll address these in a follow-up before we turn this on for fuzzing.

The instruction selector assumed for Word32AtomicPairLoad node that if there exists a Projection(1) user, then there also exists a Projection(0) user. This, however, is not the case, because TurboFan eliminates unreachable nodes. The missing projection node lead to a failed DCHECK in the register allocator. To fix the problem I use now the Word32AtomicPairLoad node directly to allocate the register. On ia32 I stop additionally to allocate unneeded temp registers.

Last uses were removed in https://crrev.com/c/1847366, thus this whole API is unused by now. This CL deprecates the API and refactors tests to use the internal APIs instead.

Add a case for kWasmS128 in Spill. We encounter this in the wasm-trace-memory-liftoff test, but that test was skipped on ARM and ARM64 due to insufficient implementation of Liftoff on those archs.

This is a pure refactoring to make the {GraphAssembler} available in all of {WasmGraphBuilder}, including {WasmWrapperGraphBuilder}. Future CLs will use more features of the {GraphAssembler} for building wasm graphs. The {WasmGraphAssembler} class will be extended to contain functionality only needed (or making sense) in the context of wasm. Drive-by: Move fields to the end of the {WasmGraphBuilder} class.

The asm.js offset table exists in two forms: Delta-encoded in a byte array, as generated during asm translation, and decoded, for faster lookup. This CL moves the encoded version from the {AsmWasmData} and {WasmModuleObject} to the {WasmModule}, and stores it off-heap in a C++ array instead of a {ByteArray}. Also, it moves the decoded version off-heap by storing it in a C++ data structure that makes lookup easy, instead of encoding it again in another {ByteArray}. This change is a nice refactoring in itself, but it also prepares adding more information to the offset table. For reconstructing the source code of an asm.js function, we will need to store the start and end offsets of the whole function as well (see linked bug).

The test was supposed to manipulate the serialized bytes to make them invalid, but the value at the manipulated position was already 0, hence the bytes stayed valid. This went unnoticed before https://crrev.com/c/2010786, since there was a fallback anyway to re-compile the module if deserialization fails. This CL fixes this by using the right offset, and checking that the value there is not already zero.

This fixes a few issues: 1) It avoids using the {DeserializeOrCompile} API method, which is not used in chrome any more and will be deprecated soon. 2) It switches to the {DeserializeNativeModule} internal method, which really checks deserialization in isolation and does not fall back to compiling the wire bytes if the serialized bytes are incorrect. 3) It disables a test which tried to invalidate the number of functions, but the respective bytes were already zero, so nothing was invalidated. This still needs to be fixed in a follow-up CL. 4) It serializes the modules in a separate isolate, which then gets disposed to free references to the NativeModule and remove it from the modules cache. Otherwise we will just never deserialize, but use the cached module instead.

Adds support to the register allocator verifier to keep track of which stack slots contain tagged pointers, but have not been tracked by the reference map and so could contain stale values (i.e., not traced by a garbage collection).
