DebugInfo: Avoid emitting constnants for every use While the folding set would deduplicate the nodes themselves and LLVM would handle not emitting the same global twice, it still meant creating a long/redundant list of global variables. llvm-svn: 205668

// RUN: %clang_cc1 -triple x86_64-none-linux-gnu -emit-llvm -g %s -o - | FileCheck %s
// Multiple references to the same constant should result in only one entry in
// the globals list.
Reapply r205655, DebugInfo: Place global constants in their appropriate context. This was reverted in 205664 and seems to be fixed by 205668... though that may be more by accident than anything well founded. llvm-svn: 205669
