This combined match/rewrite functionality allows simplifying the majority of existing RewritePatterns, as they do not benefit from separate match and rewrite functions.
Some of the existing canonicalization patterns in StandardOps have been modified to take advantage of this functionality.

truly massive patch in this refactoring.

is the new base of the SSA value hierarchy. This CL also standardizes all the
nomenclature and comments to use 'Value' where appropriate. This also eliminates a large number of cast<MLValue>(x)'s, which is very soothing.

LegalizationPatterns which will be allowed to change the types of things they
rewrite.

time. The "Fast and Flexible Instruction Selection With Constraints" paper
from CC2018 makes a credible argument that dynamic costs aren't actually
necessary/important, and we are not using them.

make operations provide a list of canonicalizations that can be applied to
them. This allows canonicalization to be general to any IR definition.
As part of this, sink PatternMatch.h/cpp down to the IR library to fix a
layering problem.
