[PATCH] D29711: [globalisel] Sort RuleMatchers by priority.

[Daniel Sanders via Phabricator via llvm-commits]

dsanders created this revision.
Herald added subscribers: kristof.beyls, dberris.

This makes more important rules have priority over less important rules.
For example, '%a = G_ADD $b:s64, $c:s64' has priority over
'%a = G_ADD $b:s32, $c:s32'. Previously these rules were emitted in the
correct order by chance.

NFC in this patch but it is required to make the next patch work correctly.

Depends on https://reviews.llvm.org/D29710
