Rename `compute_x` methods
r? ```@lcnr```
I find the `compute_x` naming scheme to be overly confusing. It means `compute_wf_obligations_for_x_and_add_them_to_self` but shortens out all of the important parts of the actual operation being performed. `compute_x` sounds like its somehow performing `x`, maybe even returning it from the function, which is not true.
I've had some newer contributors be confused by this naming scheme so I think it's good to change it to something more self-evident
Some misc drive by niceties while I was here too.
