This option has been enabled by default for quite a while now. The practical impact of removing the option is that MSSA use cannot be disabled in default pipelines (both LPM and NPM) and in manual LPM invocations. NPM can still choose to enable/disable MSSA using `loop` vs `loop-mssa`.

The next step will be to require MSSA for LICM and drop the AST-based implementation.
