Allow running mjsunit/manual-parallel-recompile on single-core systems. · f8fc5c44

palfia@homejinni.com authored Jun 17, 2013

- 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.
