The name {kLastErrorMessage} is misleading, as it's not actually the index of the last message (or reason), but one more (i.e. number of messages / reasons). Thus this renaming.

For checks and assertions (mostly for debug code, like stack alignment or zero extension), we had two modes: Emit a call to the {Abort} runtime function (the default), and emit a debug break (used for testing, enabled via --trap-on-abort). In wasm, where we cannot just call a runtime function because code must be isolate independent, we always used the trap-on-abort behaviour. This causes problems for our fuzzers, which do not catch SIGTRAP, and hence do not detect debug code failures. This CL introduces a third mode ("hard abort"), which calls a C function via {ExternalReference}. The C function still outputs the abort reason, but does not print the stack trace. It then aborts via "OS::Abort", just like the runtime function. This will allow fuzzers to detect the crash and even find a nice error message. Even though this looks like a lot of code churn, it is actually not. Most added lines are new tests, and other changes are minimal.

The most important point of IWYU (include-what-you-use) is that each header includes everything it is using, so that whoever includes that header does not need to additionally include other things. This CL adds a script which generates files to automatically check this. It is automatically invoked during "gclient runhooks" if the "check_v8_header_includes" variable is set. This script generates a number of .cc files in the "check-header-includes" directory, together with a "sources.gni" file which lists all the generated cc files. Each file includes one header. If additionally the gn args "v8_check_header_includes" is set, this gni file is included, and all the generated CC files will be compiled. This will detect violations of the aforementioned IWYU rule.

Currently AtomicStores use AtomicExchange to store to memory, but AtomicExchange produces an output that is ignored by the AtomicStore visitor, a side effect of this is that a register already in use gets overwritten by the output of the exchange.

This CL changes Array.p.fill to use the baseline implementation for everything other than JSArray. One of the reasons is that shadowing the length property on TypedArrays (and other ElementsKinds) is allowed and should be respected by Array.p.fill. The fast-path for fill for TypedArrays expects the indices to be clamped to the actual length of the underlying backing store and not to some length property. While this mismatch (and others) could probably be handled properly, we do the conservative thing and only use the fast-path for specific JSArrays.
