This pull request port `regallocfast` to new pass manager. It exposes the parameter `filter` to handle different register classes for AMDGPU. IIUC AMDGPU need to allocate different register classes separately so it need implement its own `--<reg-class>-regalloc`. Now users can use e.g. `-passe=regallocfast<filter=sgpr>` to allocate specific register class. The command line option `--regalloc-npm` is still in work progress, plan to reuse the syntax of passes, e.g. use `--regalloc-npm=regallocfast<filter=sgpr>,greedy<filter=vgpr>` to replace `--sgpr-regalloc` and `--vgpr-regalloc`.
