refactor: more idiomatic syntax for if h: (#5567) 
https://github.com/leanprover/lean4/pull/5552 introduced a fair number
of `if h:`, but the slightly preferred style is `if h :`, with a space,
so here goes a quick `sed`.

913ca41129 refactor: merge lcAny and lcErased 
`lcErased` is a superset of `lcAny` anyway, and we didn't find ways of
using the distinction to generate better code.

c1b7accd12 refactor: LCNF local context 
The previous implementation had a few issues:
- Function (and join point) declarations were being inserted into two different hashmaps.
- `borrow` information was not available for parameters.
- No proper erase functions.
