2a940dd4ae feat: add Expr.collectFVars, LocalDecl.collectFVars, Pattern.collectFVars, and AltLHS.collectFVars 
They are all in `MetaM`.

These are helper functions for issue #1237. We need to "cleanup" the
local context before trying to compile the match-expression.

see issue #1237

09d1530d8e feat: detect unexpected occurrences of match-expression minor premises 
The error message is far from perfect, but it is better than ignoring
the issue and failing later with an even more incomprehensible error
message.
