Matthew Voss	fe50eac85c	[llvm-reduce] Fix di-metadata pass test failures ... We're seeing intermittent failures in upstream bots. See: https://lab.llvm.org/buildbot/#/builders/139/builds/29185 https://lab.llvm.org/buildbot/#/builders/238/builds/295 This appears to be due to the unstable iteration order of DenseSet. Since we're trying to reduce a tree, it makes sense to attempt reductions from the top down. This also addresses post-review comments from @MatzeB.

Matthew Voss	2c799b7793	[llvm-reduce] Add pass that reduces DebugInfo metadata ... This new pass for llvm-reduce attempts to reduce DebugInfo metadata. The process used is: 1. Scan every MD node, keeping track of nodes already visited. 2. Look for DebugInfo nodes, then record any operands that are lists. 3. Bisect though all the elements of the collected lists.
