Bug 18527 – lldb: `frame variable` works with ldc2, not with dmd

``` dmd -g main.d lldb main b some_function r fr v ``` doesn't show any local variable it works with s/dmd/ldc2

It seems like GDB on macOS works, but not LLDB. DMD need to follow the LLVM tools on macOS, not the GNU tools. In this case Clang and LLDB. Bumping to critical.
