Fix PR 107734: valgrind errors with sbitmap in match.pd
sbitmap is a simple bitmap and the memory allocated is not cleared
on creation; you have to clear it or set it to all ones before using
it. This is unlike bitmap which is a sparse bitmap and the entries are
cleared as created.
The code added in r13-4044-gdc95e1e9702f2f missed that.
This patch fixes that mistake.
Committed as obvious after a bootstrap and test on x86_64-linux-gnu.

* match.pd (perm + vector op pattern): Clear the sbitmap before
use.
