Teach combineMetadata how to merge 'nonnull' metadata.
combineMetadata is used when merging two instructions into one. This change teaches it how to merge 'nonnull' - i.e. only preserve it on the new instruction if it's set on both sources. This isn't actually used yet since I haven't adjusted any of the call sites to pass in nonnull as a 'known metadata'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220325 91177308-0d34-0410-b5e6-96231b3b80d8
