This is a reland of ed7e4554db:
- fixing platform names for tickprocessor
- UnixCppEntriesProvider => LinuxCppEntriesProvider
- MacCppEntriesProvider => MacOSCppEntriesProvider
Original change's description:
> [mjsunit][tools][d8] Full roundtrip tickprocessor test
>
> - Add os.d8Path property
> - Add os.name property
> - Change tickprocssor test to use command line arguments for testing
> various configurations
> - Change tickprocessor test to create a temporary v8.log and read it
> back in on linux only
> - Rearrange code in tickprocessor.mjs to allow instantiating the
> CppEntriesProvider directly
> - Drop complete symbol-list for tickprocessor-test-large.log for better
> code searching in V8
>
