Transforms: Update unit tests to use verifyModule()
Since I'm slowly gutting `DISubprogram` and `DICompileUnit`, update the
`CloneFunc` unit tests to call `verifyModule()` (where the checks are
moving to).

DebugInfo: Remove dead code from old DebugLoc API
Remove old API for `DebugLoc` now that all the callers have been
updated. If this broke your out-of-tree build, here's a quick map from
the old API to the new one:
DebugLoc DebugLoc::getFromMDLocation(MDNode *)
=> DebugLoc::DebugLoc(MDLocation *)
=> explicit DebugLoc::DebugLoc(MDNode *) // works with broken code
MDNode *DebugLoc::getAsMDNode(LLVMContext &)
=> MDLocation *DebugLoc::get()
=> DebugLoc::operator MDLocation *()
=> MDNode *DebugLoc::getAsMDNode() // works with broken code
bool DebugLoc::isUnknown()
=> DebugLoc::operator MDLocation *()
i.e.: if (MDLocation *DL = ...)
=> DebugLoc::operator bool() // works with broken code
i.e.: if (DebugLoc DL = ...)
void DebugLoc::getScopeAndInlinedAt(MDNode *&, MDNode *&)
=> use: MDNode *DebugLoc::getScope()
and: MDLocation *DebugLoc::getInlinedAt()
MDNode *DebugLoc::getScopeNode(LLVMContext &)
=> MDNode *DebugLoc::getInlinedAtScope()
void DebugLoc::dump(LLVMContext &)
=> void DebugLoc::dump()
void DebugLoc::getFnDebugLoc(LLVMContext &)
=> void DebugLoc::getFnDebugLoc()
MDNode *DebugLoc::getScope(LLVMContext &)
=> MDNode *DebugLoc::getScope()
MDNode *DebugLoc::getInlinedAt(LLVMContext &)
=> MDLocation *DebugLoc::getInlinedAt()
I've noted above the only functions that won't crash on broken code (due
to downcasting to `MDLocation`). If your code could be dealing with
broken IR (i.e., you haven't run the verifier yet, or you've used a
temporary node that will eventually (but not yet) get RAUW'ed to an
`MDLocation`), you need to restrict yourself to those.

[analyzer] Disable all retain count diagnostics on values that come from ivars.
This is imitating a pre-r228174 state where ivars are not considered tracked by
default, but with the addition that even ivars /with/ retain count information
(e.g. "[_ivar retain]; [ivar _release];") are not being tracked as well. This is
to ensure that we don't regress on values accessed through both properties and
ivars, which is what r228174 was trying to fix.
The issue occurs in code like this:
[_contentView retain];
[_contentView removeFromSuperview];
[self addSubview:_contentView]; // invalidates 'self'
[_contentView release];
In this case, the call to -addSubview: may change the value of self->_contentView,
and so the analyzer can't be sure that we didn't leak the original _contentView.
This is a correct conservative view of the world, but not a useful one. Until we
have a heuristic that allows us to not consider this a leak, not emitting a
diagnostic is our best bet.
This commit disables all of the ivar-related retain count tests, but does not
remove them to ensure that we don't crash trying to evaluate either valid or
erroneous code. The next commit will add a new test for the example above so
that this commit (and the previous one) can be reverted wholesale when a better
solution is implemented.
