Move the calling of emitTargetMD() later.

Summary:
Because a global created by GetOrCreateLLVMGlobal() is not finalised until later viz:
  extern char a[];
  char f(){ return a[5];}
  char a[10];

Change MangledDeclNames to use a MapVector rather than a DenseMap so that the
Metadata is output in order of original declaration, so to make deterministic
and improve human readablity.
