IR: Use ODR to unique DICompositeType members
Merge members that are describing the same member of the same ODR type,
even if other bits differ. If the file or line differ, we don't care;
if anything else differs, it's an ODR violation (and we still don't
really care).
For DISubprogram declarations, this looks at the LinkageName and Scope.
For DW_TAG_member instances of DIDerivedType, this looks at the Name and
Scope. In both cases, we know that the Scope follows ODR rules if it
has a non-empty identifier.
