prologue is handled in the line table. We now mark the first instruction after the stack setup as end_prologue and any further initilizations (which may include function calls to metadata accessors) with line 0 which lldb will skip. This allows swiftc to emit debug info for compiler-generated functions such as metadata accessors. Mixing debug and non-debug functions is not very well supported by LLVM and the resulting line table makes it impossible for LLDB to determine where a function with debug info ends and a nondebug function starts. rdar://problem/23042642 Swift SVN r32816
