it is both inefficient and unexpected by dwarfdump. Change to

While in here, change the predicate name to reflect that the position
is not really absolute (it is an offset), just that the linker needs a

Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, and
...
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.
