Reduce the dispatching overhead in the hottest loop when parsing log-lines.
- Using a JSMap we can avoid internalizing strings
- Preprocess the dispatch table and only have varArgs or functions as
parsers
- string[] seems to be slightly faster than string.charAt()

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

For simplicity this CL includes a first crude conversion of
tickprocessor.mjs. Later CLs will introduce more ES6 syntax and clean
up more code.

This is mostly an auto-conversion done by several tools.
- use let / const
- use arrow functions
- use template strings
There are some additional manual rewrite required to modernize the
code further.

Convert Profile, CodeMap and their helpers to ES6 classes.
Code cleanup will happen in a separate step.
