[PATCH] D102356: [UniqueLinkageName] Use exsiting GlobalDecl object instead of reconstructing one.

C++ constructors/destructors need to go through a different constructor to construct a GlobalDecl object in order to retrieve their linkage type. This causes an assert failure in the default constructor of GlobalDecl. I'm chaning it to using the exsiting GlobalDecl object.
