- Add an %IsParallelSupported() builtin function to make possible to check support of parallel processing from JavaScripts. - Change the test script that if parallel recompilation is forced on a single core CPU, expect that it won't be recompiled in parallel. - Change the JSFunction::MarkForParallelRecompilation() to fall back gracefully if parallel recompilation is not supported.
