alongside DIEBlock and replace uses accordingly. Use DW_FORM_exprloc in DWARF4 and later code. Update testcases. Adding a DIELoc instead of using extra forms inside DIEBlock so that we can keep location expressions separate from other uses. No direct use at the moment, however, it's not a lot of code and using a separately named class keeps it somewhat more obvious what's going on in various locations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201481 91177308-0d34-0410-b5e6-96231b3b80d8
