Reid Kleckner 6d353348e5 Parse and print DIExpressions inline to ease IR and MIR testing

Summary:
Most DIExpressions are empty or very simple. When they are complex, they
tend to be unique, so checking them inline is reasonable.

This also avoids the need for CodeGen passes to append to the
llvm.dbg.mir named md node.

See also PR22780, for making DIExpression not be an MDNode.

README

This directory contains tests for the MIR file format parser and printer. It
was necessary to split the tests across different targets as no single target
covers all features available in machine IR.

Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As
a rule of thumb this directory should only contain tests using
'llc -run-pass none'.
