Amend match.pd syntax with force-simplified results
This adds a ! marker to result expressions that should simplify
(and if not fail the simplification). This can for example be
used like
(simplify
(plus (vec_cond:s @0 @1 @2) @3)
(vec_cond @0 (plus! @1 @3) (plus! @2 @3)))
to make the simplification only apply in case both plus operations
in the result end up simplified to a simple operand.

* genmatch.c (expr::force_leaf): Add and initialize.
(expr::gen_transform): Honor force_leaf by passing
NULL as sequence argument to maybe_push_res_to_seq.
(parser::parse_expr): Allow ! marker on result expression
operations.
* doc/match-and-simplify.texi: Amend.
