  [SandboxIR] Fix pass pipeline parsing after aux arguments

After parsing a pass aux argument, resume scanning pass names instead of
args when the next token is a delimiter. This allows flat pipelines like
foo(aux),bar to be parsed correctly.

  [SBVec] Implement topDown/botUp vectorizers in unison

This patch introduces the `top-down-vec` pass to the Sandbox Vectorizer,
adding the ability to traverse use-def chains top-down to discover and
collect vectorization opportunities. Furthermore, this patch unifies
the two vectorizers into a single implementation to minimize code
duplication.
