Fix the compilation of pattern matching wrt to variables.

Compilation of pattern-matching used to systematically introduce a dummy alias x:=x in the typing environment for each variable x in the patterns (except for purely variable patterns which correctly alias the term being matched). This interfered badly with the new refine implementation.

To correct this I changed the "all variables" case of pattern-matching compilation to check whether the term currently being matched is a term introduced by the user or a subterm which is necessarily a variable. In the latter case, no alias is introduced.
