Moved grammar and parser generation scripts to batch compiler (eclips…

…e-jdt#181)

- Grammar file belongs to compiler, build scripts for it too.
- Added grammar to sources.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=562044 for original
contribution motivation for parser build scripts. No idea if the code
still works and no idea where to get the *right* native JikesPG
executable, so I can't test if that works or not.

See eclipse-jdt#181
