matcher: remove duplicate variables in one place.

* share/txr/stdlib/match.tl (compiled-match get-var-exprs):
method get-var-exprs removed. This is only used in one place,
which is going away. Actually, the value is not even used; it
is discarded.
(compiled-match get-vars): This method now passes the list of
variables thorugh uniq. The logic of get-guard-values is
pulled into a local function, since get-guard-values has only
one caller now.
(get-guard-values): Function removed.
(compile-or-match): Removing all-var-exprs variable
and all that calculation of the unique names, as well as the
extra match-guard which duplicates those names pointlessly.
