Chandler Carruth bbc434b85c Simplify the PatternMatch unittest by giving it a module, function, and
basic block to hold instructions, and managing all of their lifetimes in
a fixture. This makes it easy to sink the expectations into the test
cases themselves which also makes things a bit more explicit and clearer
IMO.
