[X86] Improved lowering of v4x32 build_vector dag nodes.
This patch improves the lowering of v4f32 and v4i32 build_vector dag nodes
that are known to have at least two non-zero elements.
With this patch, a build_vector that performs a blend with zero is
converted into a shuffle. This is done to let the shuffle legalizer expand
the dag node in a optimal way. For example, if we know that a build_vector
performs a blend with zero, we can try to lower it as a movq/blend instead of
always selecting an insertps.
This patch also improves the logic that lowers a build_vector into a insertps
with zero masking. See for example the extra test cases added to test sse41.ll.

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.

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.

Make the ASan OS X DYLD_INSERT_LIBRARIES detection path-independent
Reviewed at http://reviews.llvm.org/D6238
ASan on Darwin during launch reads DYLD_INSERT_LIBRARIES env. variable and if it's not set or if the ASan dylib is not present in there, it relaunches the process. The check whether the dylib is present in the variable is now trying to find a full path in there. This fails in the scenarios where we want to copy the dylib to the executable's directory or somewhere else and set the DYLD_INSERT_LIBRARIES manually, see http://reviews.llvm.org/D6018.
Let's change the search in DYLD_INSERT_LIBRARIES to only look for the filename of the dylib and not the full path.
