brw: Move into a new src/intel/compiler/brw subdirectory

This keeps the directory structure a bit more organized:
- brw specific code
- elk specific code
- common NIR passes that could be used in both places

It also means that you can now 'git grep' in the brw directory without
finding a bunch of elk code, or having to "grep thing b*".
