always selecting an insertps.

Fix tail recursion elimination
When the BasicBlock containing the return instrution has a PHI with 2
incoming values, FoldReturnIntoUncondBranch will remove the no longer
used incoming value and remove the no longer needed phi as well. This
leaves us with a BB that no longer has a PHI, but the subsequent call
to FoldReturnIntoUncondBranch from FoldReturnAndProcessPred will not
remove the return instruction (which still uses the result of the call
instruction). This prevents EliminateRecursiveTailCall to remove
the value, as it is still being used in a basicblock which has no
predecessors.
The basicblock can not be erased on the spot, because its iterator is
still being used in runTRE.

Remove StringMap::GetOrCreateValue in favor of StringMap::insert
Having two ways to do this doesn't seem terribly helpful and
consistently using the insert version (which we already has) seems like
it'll make the code easier to understand to anyone working with standard
data structures. (I also updated many references to the Entry's
key and value to use first() and second instead of getKey{Data,Length,}
and get/setValue - for similar consistency)
Also removes the GetOrCreateValue functions so there's less surface area
to StringMap to fix/improve/change/accommodate move semantics, etc.

Overhaul and separate nullptr_t tests to pass with C++03.
The standard requires that nullptr_t can be reinterpret_cast to an integral type
at least the size of nullptr_t. There is no way to emulate this conversion in
the C++03 nullptr_t implementation. The test for this conversion has been moved
to a new test and marked XFAIL with c++03.
This recommits what was originally r222296.

Make StringSet::insert return pair<iterator, bool> like other self-associative containers
StringSet is still a bit dodgy in that it exposes the raw iterator of
the StringMap parent, which exposes the weird detail that StringSet
actually has a 'value'... but anyway, this is useful for a handful of
clients that want to reference the newly inserted/persistent string data
in the StringSet/Map/Entry/thing.

Add additional checks to the SavedLocationForRegister method
where it is retrieving the Return Address register contents
on a target where that's a thing. If we fail to get a valid
RA, we force a switch to the fallback unwind plan. This patch
adds a sanity check for that fallback unwind plan -- it must
get a valid CFA for this frame in addition to being able to
retrieve the caller's PC -- and it correctly marks the unwind
rules as failing if the fallback unwind plan fails.

[mach-o] propagate dylib version numbers
Mach-o does not use a simple SO_NEEDED to track dependent dylibs. Instead,
the linker copies four things from each dylib to each client: the runtime path
(aka "install name"), the build time, current version (dylib build number), and
compatibility version The build time is no longer used (it cause every rebuild
of a dylib to be different). The compatibility version is usually just 1.0
and never changes, or the dylib becomes incompatible.
This patch copies that information into the NormalizedMachO format and
propagates it to clients.
