c1339240cd RequirementMachine: Add flags to enable and disable merged associated types
On by default, no change from current behavior. I'm going to try turning
this off (and hopefully ripping it out entirely) once I fix a few bugs.

2f2249cef1 RequirementMachine: Fix various RewriteSteps to work when re-contextualized
When a rewrite rule is replaced with a path containing ::Adjust, ::Decompose,
::ConcreteConformance or ::SuperclassConformance rewrite steps, the steps
will get a non-zero EndOffset if the original rule appears in a step with a
non-zero EndOffset.

For this reason, these steps must work with a non-zero EndOffset, which
primarily means computing correct offsets into the term being manipulated.
