Samuel Benzaquen 7ec2cb2fda Separate the matchers by type and statically dispatch to the right list.
Summary:
Separate the matchers by type and statically dispatch to the right list.
For any node type that we support, it reduces the number of matchers we
run it through.
For node types we do not support, it makes match() a noop.
This change improves our clang-tidy related benchmark by ~30%.
