72bb40229e Treat [1 x i8] zeroinitializer as a C string, placing such stuff into 
mergeable string section. I don't see any bad impact of such decision
(rather then placing it into mergeable const section, as it was before),
but at least Darwin linker won't complain anymore.

The problem in LLVM is that we don't have special type for string constants
(like gcc does). Even more, we have two separate types: ConstatArray for non-null
strings and ConstantAggregateZero for null stuff.... It's a bit weird :)

5df3186f59 Rename isWeakForLinker to mayBeOverridden. Use it 
instead of hasWeakLinkage in a bunch of optimization
passes.

d2e51af035 Move the uglier parts of deciding not to emit a 
UsedDirective for some symbols in llvm.used into
Darwin-specific code.  I've decided LessPrivateGlobal
is potentially a useful abstraction and left it in
the target-independent area, with improved comment.
