Remove support for DIVariable's FlagIndirectVariable and expect
frontends to use a DIExpression with a DW_OP_deref instead. This is not only a much more natural place for this informationl; there is also a technical reason: The FlagIndirectVariable is used to mark a variable that is turned into a reference by virtue of the calling convention; this happens for example to aggregate return values. The inliner, for example, may actually need to undo this indirection to correctly represent the value in its new context. This is impossible to implement because the DIVariable can't be safely modified. We can however safely construct a new DIExpression on the fly. llvm-svn: 226476
