Debug Info: Use identifier to reference DIType in base type field of ptr_to_member. We introduce a new class DITypeRef that represents a reference to a DIType. It wraps around a Value*, which can be either an identifier in MDString or an actual MDNode. The class has a helper function "resolve" that finds the actual MDNode for a given DITypeRef. We specialize getFieldAs to return a field that is a reference to a DIType. To correctly access the base type field of ptr_to_member, getClassType now calls getFieldAs<DITypeRef> to return a DITypeRef. Also add a typedef for DITypeIdentifierMap and a helper generateDITypeIdentifierMap in DebugInfo.h. In DwarfDebug.cpp, we keep a DITypeIdentifierMap and call generateDITypeIdentifierMap to actually populate the map. Verifier is updated accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190081 91177308-0d34-0410-b5e6-96231b3b80d8

Debug Info: instead of calling addToContextOwner which constructs the context after the DIE creation, we construct the context first. Ensure that we create the context before we create a type so that we can add the newly created type to the parent. Remove last use of addToContextOwner now that it's not needed. We use createAndAddDIE to wrap around "new DIE(". Now all shareable DIEs should be added to their parents right after the creation. Reviewed off-list by Eric, Thanks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193657 91177308-0d34-0410-b5e6-96231b3b80d8

DebugInfo: Remove some unneeded conditionals now that DIBuilder no longer emits zero-length arrays as {i32 0} A bunch of test cases needed to be cleaned up for this, many my fault - when implementid imported modules I updated test cases by simply duplicating the prior metadata field - which wasn't always the empty metadata entry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200731 91177308-0d34-0410-b5e6-96231b3b80d8
