Don't compose DWARF expressions with multiple subregisters. If a register location can only be described by a complex expression (i.e., multiple subregisters) it doesn't safely compose with another complex expression. For example, it is not possible to apply a DW_OP_deref operation to multiple DW_OP_pieces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@298389 91177308-0d34-0410-b5e6-96231b3b80d8
