It turns out that putting an 8-byte symbol in a 4-byte section makes Solaris ld sulk. GNU ld is perfectly happy with it, which is worrying for a whole other set of reasons...
...
Thanks to Anton, Duncan and Rafael for helping me track this down.
Pointy hat to Rafael for introducing the bug in the first place.

Modify the code that emits the module flags to use the new module flags accessor
...
method. This allows the target lowering code to not have to deal with MDNodes.
Also, avoid leaking memory like a sieve by not creating a global variable for
the image info section, but just emitting the code directly.

The MachO back-end needs to emit the garbage collection flags specified in the
module flags. This is a WIP, so the front-end hasn't been modified to emit these
flags just yet. Documentation and front-end switching to occur soon.

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.
