snapshot.h is intended to be the public header for the snapshot component, and not the right place for private declarations.

Clemens Backes authored
From several runtime functions, this was still missing. For some, it shouldn't really matter, but some runtime functions (e.g. DebugBreak) can call back into JS to wasm, and there it matters. As it never hurts to clear and re-set the flag, this CL consistently resets the flag for all runtime functions called from wasm code. For runtime functions that are called from outside of wasm (e.g. from wrappers), we add a DCHECK instead that the flag is not set. There is one exception (WasmThrowTypeError), which is called both from wasm code and from wrappers. In this case it's OK, I added a comment saying why. Drive-by: Remove obsolete comments (from a time where this clearing was still optional in some cases).

... between the interpreter and generated code. Prior to this CL, pre- and post conditions on the output register array differed between the interpreter and generated code. Interpreter Pre: `output` fits captures and temporary registers. Post: None. Generated code Pre: `output` fits capture registers. Post: `output` is modified if and only if the match succeeded. This CL changes the interpreter to match generated code pre- and post conditions by allocating space for temporary registers inside the interpreter. Drive-by: Add MaxRegisterCount, RegistersForCaptureCount helpers.

RegExpImpl::Compile does a number of transformations that require directly manipulating the internal representation of the regexp. For example, when matching a (non-sticky, non-anchored) regular expression, the pattern must be wrapped in .* so that it can match anywhere in the input. In the interest of moving towards a cleaner division between irregexp and the outside world, it makes sense to move this code into RegExpCompiler.

LoadCurrentCharacterImpl is implemented once in each of the eight regexp-macro-assembler-<arch>.cc files. Aside from small differences in comment wording, those eight implementations are identical. The architecture-specific code for LoadCurrentCharacter is all in LoadCurrentCharacterUnchecked. This patch hoists the definition of LoadCurrentCharacterImpl into NativeRegExpMacroAssembler and turns LoadCurrentCharacterUnchecked into a virtual function. Note: The arm64 version of LoadCurrentCharacterImpl contained the following six-year-old comment, which I don't think is worth preserving: // TODO(pielan): Make sure long strings are caught before this, and // not just asserted in debug mode.

With https://crrev.com/c/2118476, we can decode multi byte opcodes. So the module builder should be emitting the correct LEB encoded bytes for SIMD opcodes. This also fixes an error discovered by the fuzzer: I added f64x2.add to the fuzzer, but that's actually a multi-byte opcode, so it resulted in incorrect bytes generated. This should fix it.

To enable this, the following changes were necessary: - Fix generation of accessors with MaybeObject type and a bunch of include problems. - Torque-generated C++ classes now have a constructor that can allow Smi values to enable a hack currently used for the DescriptorArray.

The flag is on by default, and tests already rely on the new behaviour. This CL removes the flag and immediately affected code. More code will be removed component by component in follow-up CLs. Drive-by: Inline {RemoveBreakpointFromInfo} into {ClearBreakPoint}, which only redirected to that method after this CL.
