Assorted debug info fixes.
- DW_AT_bit_size is only suitable for bitfields.
- Encode source location info for derived types.
- Source location and type size info is not useful for subroutine_type (info is included in respective DISubprogram) and array_type.

doesn't support it. The default is set to 'true', so this should not
impact any other target backends.

DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.

Do not use DenseMap because the iterator is invalidated while constructing types. After all there was a reason why std::map was used initially!

Split Support/Registry.h into two files so that we have less to
recompile every time CommandLine.h is changed.

Removoe MachineModuleInfo methods (and related DebugInfoDesc class  hierarchy) that were used to handle debug info.

Keep "has debug info" big in MachineModuleInfo to avoid circular dependency between AsmPrinter and CodeGen.
