Make dumpPassStructure be a PMDataManager abstraction, rather than
...
a Pass abstraction, since that's the level it's actually used at.
Rename Pass' dumpPassStructure to dumpPass.
This eliminates an awkward use of getAsPass() to convert a PMDataManager*
into a Pass* just to permit a dumpPassStructure call.

Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock:

don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.
Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.

LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.

linked list. This is a little slower and involves more malloc'ing, but these lists are
typically short, and it allows PassInfo to be entirely constant initializable.

Implement the "linker_private_weak" linkage type. This will be used for
...
Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.
For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:
.globl l_objc_msgSend_fixup_alloc
.weak_definition l_objc_msgSend_fixup_alloc
.section __DATA, __objc_msgrefs, coalesced
.align 3
l_objc_msgSend_fixup_alloc:
.quad _objc_msgSend_fixup
.quad L_OBJC_METH_VAR_NAME_1
This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".
Currently only supported on Darwin platforms.
