compiler: Support the majority of the remaining VU VF instructions (#258)

Browse Source 
* compiler: Support the majority of the remaining VU VF instructions

- VWAIT
- VMADD variants
- VMSUB variants
- VSQRT
- VDIV
- outer product (VOPMULA + VOPMSUB)

* compiler: Fix some bugs / optimize some instructions

* tests/compiler: Add test coverage for new instructions

* docs: Add documentation for new inline assembly functions

* lint: Formatting / fix failing test

* Remove my comment about ftf/fsf encoding, it's been fixed

* address review feedback

* correct VSQRTPS implementation
