Move Containment Analysis to Lowering
- Ensure that the only changes to child nodes are the specification of srcCandidates
(i.e. the register requirements of the parent/consumer)
- Since this now occurs before redoing dataflow, we don't have complete information on
what lclVars are containable. To mitigate this:
- In `TreeNodeInfoInit()`, if a lclVar is marked `isRegOptional` but is now untracked,
change it to be contained.
- Mark decomposed/promoted fields of long params as `lvDoNotEnregister`
- Ensure that any new code added after `Lowering` is analyzed as necessary.
- When a value becomes unused, it is no longer contained. (This is needed now because liveness runs after containment analysis)
- Add dumping of nodes deleted as unused.
- Need to set byteable regs, as needed on contained RMW memory ops.
