Fix XCoreLowerThreadLocal trying to initialise globals which have no initializer. Add handling of const expressions containing thread local variables. These need to be replaced with instructions, as the thread ID is used to access the thread local variable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190300 91177308-0d34-0410-b5e6-96231b3b80d8
