Geoff Romer 223c5cb04b Restructure handling of runtime parameters (#4422) 
- Generate runtime indices as part of pattern matching, rather than as a
separate postprocessing/rewriting step.
- In contexts where runtime parameters aren't permitted, avoid emitting
insts for them to begin with, rather than trying to detect the problem
and rewrite the IR to remove them later on.
