* A little project cleanup

* Script to grep decompiler results

* Compiler: Implement VNOP -> FNOP (.nop.vf)


temp: test new addition

* Compiler: Implement VMUL.xyzw (.mul.vf)


squash: cleaning up files i don't want to accidentally stage

* Compiler: Implement V[ADD|SUB|MUL].dest instructions

* Compiler:  Implement V[ADD|SUB|MUL][x|y|w|z].dest instructions

* Compiler: Implement V[MIN|MAX]{[x|y|z|w]}.dest instructions

* Compiler: Implement V[ABS]{[x|y|z|w]}.dest instructions

* Cleanup review feedback before adding tests and docs

* Tests: Added missing emitter tests

* tests/compiler: Comprehensively test all new instructions

* docs: Add documentation for newly supported operations
