Ahmed Bougacha 982c5eb396 [GlobalISel] Return an Expected<RuleMatcher> for each SDAG pattern. NFC.
Instead of emitting the matcher code directly, return the rule matcher
and the skip reason as an Expected<RuleMatcher>.

This will let us record all matchers and process them before emission.

It's a somewhat unconventional use of Error, but it's nicer than, say,
std::pair, because of the bool conversions.
