Michael Starzinger authored
This adds initial support for concurrently patching jump table slots. It is needed once different Isolates share code (for the --wasm-shared-code feature). We need to ensure that instructions holding the target address within a jump table slot do not cross cache-line boundaries. To do this, the jump table has been split into consecutive pages. Note that this also adds a stress test for multiple threads hammering at a single slot concurrently. The test is currently limited to the ia32 and the x64 architecture, but will be extended to cover others. The test reliably triggers tearing of the target address on almost every run of the test and hence serves to prevent regressions.

For async instantiation of WebAssembly code we had the assumption that a pending exceptions (an exception which comes from execution JS code) and an ErrorThrower error cannot occur at the same time. This assumption turned out to be wrong. With this CL we handle this case by prefering pending_exceptions over ErrorThrower errors. In addition I extended the tests for failing instantiation to also exercise async instantiation, and I added a regression test.

Previously, Intl.PluralRules was mostly implemented in JavaScript. This patch moves most of the constructor and parts of other methods to C++. The size of the Intl.PluralRules object is reduced by not storing MinimumIntegerDigits, MinimumFractionDigits, MaximumFractionDigits, MinimumSignificantDigits, MaximumSignificantDigits. Instead these are looked up from icu::DecimalFormat as required. Another optimziation is that we don't create the result of resolvedOptions when the Intl.PluralRules object is constructed, but instead defer until this method is called. In the future, we may want to cache the result. This patch also cleans up several error handling paths that shouldn't happen with ICU and instead just crashes should it ever happen.
