- Explicitly document that `*Param` and `*ParamPattern` insts represent `Call` parameters. - Stop wrapping compile-time parameter patterns in `ValueParamPattern` insts (because they aren't `Call` parameters). - Document how `MatchContext::results_` relates to the `Call` parameters, and be more consistent about when it's written to. - Remove `RuntimeParamIndex::Unknown`: we no longer need to distinguish "this `Param`'s runtime index is unknown" from "this `Param` isn't a runtime param", because we no longer use `Param`s at all in the latter case. - Rename `RuntimeParamIndex` to `CallParamIndex`. As a side effect of removing the `ValueParamPattern` insts, this fixes a minor diagnostic bug where `NoteInitializingParam` didn't identify the specific parameter that led to a deduction failure, because it expects generic parameters to only be represented by `SymbolicBindingPattern`s, but before this change they could be wrapped in `ValueParamPattern`s.
