It seems to me, that simple strings / bools there are not enough :)
"$non_lazy_ptr" emission is already in asm printers (in 2 places!). The
"L" prefix is PrivateGlobalPrefix (so PersonalityPrefix is really
duplicate). That's why I thought about factoring such stuff into
separate hooks. I'm really worrying, that number of such strings / bools
can be increased, if somebody will try to make other targets (e.g. ppc /
arm) fully support things, which are now x86-specific (I even don't
know, whether current settings are enough to representing 64-bit
specific information)

I'm happy for this fix in short-term. But yes, it is pretty non-small
project :)
