This fixes how arguments of a call to {fround} are being parsed. It now accepts a single "AssignmentExpression" only instead of an "Expression" which could potentially be a whole comma-separated list of expressions.

This loads the call builtin from the Isolate root instead of embedding it into the instruction stream. This can be more efficient, but more importantly it fixes an issue with tracing and eventually allows for background compilation of these wrappers.

In the {Fixed} variant, the {GrowingVsFixedModule} test first reserves 1GB of memory, then allocates another 1GB to add it to the module as code. This uses too much memory on win32, making the test fail. Before this CL, the {NativeModule} only reserved 128kB upfront (in contrast to the actual expectation of the test). Since all other aspects of this test are already covered by other tests, we just skip this test on win32. This allows us to resolve the TODO. Drive-by: Clean up the unittests status file a bit.

This cl adds support for top level await to d8, but still does not allow top level await through parsing.

If we can read an object's Map pointer but not any data from the Map itself, we may still be able to accurately describe the object's type if the Map pointer matches one of the known Maps from the snapshot. GetObjectProperties uses that data in one of two ways: - If it is sure that the Map pointer matches a known Map, then it uses the type from that Map and continues as if it read the type normally. - If the Map pointer is at the right offset within a heap page to match a known Map, but the caller didn't provide the addresses of the first pages in Map space or read-only space, then the type of that Map is just a guess and gets returned in a separate array. This gives the caller the opportunity to present guessed types to the user, and perhaps call again using the guessed type as the type hint.

This CL enables regexp interpreter and tier-up to the compiler after one execution by setting the --regexp-tier-up flag to true by default. The number of times a regexp is interpreted before tiering-up is controlled by the --regexp-tier-up-ticks flag which is already set to 1 by default.

The predictable platform can make tasks deadlock if the spawning task is holding a lock that the spawn task also wants to take. This is because the spawned task is just executed immediately within the "context" of the spawning task. The wasm async compile tests deadlock because the {BackgroundCompileTask}s hold the shared {BackgroundCompileToken} (reader lock) while spawning new tasks via {OnBackgroundTaskStopped} -> {RestartBackgroundTasks}. The new tasks might want to cancel compilation via {BackgroundCompileToken::Cancel}, which takes the writer lock and hence deadlocks. This can not happen on any other platform, since tasks are not nested that way.

With --wasm-far-jump-table, it will be possible to create 10k (and more) modules in one process. So far, we hit the virtual address space limit around 1k modules, because each module makes a reservation of {kMaxWasmCodeMemory} upfront. After this change, each module will only reserve the estimated needed code size (if --wasm-far-jump-table is set). The test is carefully optimized to not execute too much code in the loop, so it can still run in simulators in reasonable time. Note that the time for actually compiling the module is spent in C++, which is fast in simulator builds.

The CPURegister class has an additional "type" field to represent an invalid register while the cross-platform RegisterBase class uses -1 as a register code. For consistency and to avoid potential bugs from confusing x0 and `CPURegister::no_reg()`, use -1 as a register code as well in CPURegister.
