give it a bit more responsibility. Also implement it for MachO.

If hacked to use cfi, 32 bit MachO will produce

.cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr

and 64 bit will produce

.cfi_presonality ___gxx_personality_v0

The general idea is that .cfi_personality gets passed the final symbol. It is
up to codegen to produce it if using indirect representation (like 32 bit
MachO), but it is up to MC to decide which relocations to create.

        .comm   _i,4,2                  ## @i
                                        ## @i

instead emit:
        .comm   _i,4,2                  ## @i

Let dwarf writer allocate extra space in the debug location expression. This space, if requested, will be used for complex addresses of the Blocks' variables.

Change ELF systems to use CFI for producing the EH tables. This reduces the

Remove extra bytes that were added for gdb.  We do not have good poiner to understand actual reason behind this fixme. Spot checking suggest that newer gdb does not need this.

This mechanical patch moves type handling into CompileUnit from DwarfDebug. In case of multiple compile unit in one object file, each compile unit is responsible for its own set of type entries anyway. This refactoring makes this obvious.
