Ensure that the identifier chains have the most recent declaration after module deserialization.
This commit introduces a set of related changes to ensure that the
declaration that shows up in the identifier chain after deserializing
declarations with a given identifier is, in fact, the most recent
declaration. The primary change involves waiting until after we
deserialize and wire up redeclaration chains before updating the
identifier chains. There is a minor optimization in here to avoid
recursively deserializing names as part of looking to see whether
top-level declarations for a given name exist.
A related change that became suddenly more urgent is to property
record a merged declaration when an entity first declared in the
current translation unit is later deserialized from a module (that had
not been loaded at the time of the original declaration). Since we key
off the canonical declaration (which is parsed, not from an AST file)
for emitted redeclarations, we simply record this as a merged
declaration during AST writing and let the readers merge them.

Reformat lines if they were "moved around".
An unwrapped line can get moved around if there is no newline before
it and the previous line was formatted.
Example:
template<typename T> // Cursor is on this line when hitting "format"
T *getFETokenInfo() const { return static_cast<T*>(FETokenInfo); }
"return .." is the second unwrapped line in this scenario. I does not
touch any reformatted region. Thus, the result of formatting is:
template <typename T> T *getFETokenInfo() const { return static_cast<T *>(FETokenInfo); }
After second format (and arguably desired end-result):
template <typename T> T *getFETokenInfo() const {

BBVectorize: Fix an invalid reference bug
This fixes PR15289. This bug was introduced (recently) in r175215; collecting
all std::vector references for candidate pairs to delete at once is invalid
because subsequent lookups in the owning DenseMap could invalidate the
references.
bugpoint was able to reduce a useful test case. Unfortunately, because whether
or not this asserts depends on memory layout, this test case will sometimes
appear to produce valid output. Nevertheless, running under valgrind will
reveal the error.

There seems to be some kind of incompatibility between clang and gcc here, but
I can't fathom who's right.

Remove use of reverse iterators in repairIntervalsInRange(). While they were
arguably better than forward iterators for this use case, they are confusing and
there are some implementation problems with reverse iterators and MI bundles.

Re-apply r174919 - smarter copy/move assignment/construction, with fixes for
bitfield related issues.
The original commit broke Takumi's builder. The bug was caused by bitfield sizes
being determined by their underlying type, rather than the field info. A similar
issue with bitfield alignments showed up on closer testing. Both have been fixed
in this patch.

[CodeGen] tighten objc ivar invariant.load attribution
An ivar ofset cannot be marked as invariant load in all cases. The ivar offset
is a lazily initialised constant, which is dependent on an objc_msgSend
invocation to perform a fixup of the offset. If the load is being performed on
a method implemented by the class then this load can safely be marked as an
inviarant because a message must have been passed to the class at some point,
forcing the ivar offset to be resolved.
An additional heuristic that can be used to identify an invariant load would be
if the ivar offset base is a parameter to an objc method. However, without the
parameters available at hand, this is currently not possible.

Fix a conversion from a forward iterator to a reverse iterator in
MachineBasicBlock::SplitCriticalEdge. Since this is an iterator rather than
an instr_iterator, the isBundled() check only passes if getFirstTerminator()
returned end() and the garbage memory happens to lean that way.
Multiple successors can be present without any terminator instructions in the
case of exception handling with a fallthrough.

Add support for updating the LiveIntervals of registers used by 'exotic'
terminators that actually have register uses when splitting critical edges.
This commit also introduces a method repairIntervalsInRange() on LiveIntervals,
which allows for repairing LiveIntervals in a small range after an arbitrary
target hook modifies, inserts, and removes instructions. It's pretty limited
right now, but I hope to extend it to support all of the things that are done
by the convertToThreeAddress() target hooks.

The transform is:
(or (bool?A:B),(bool?C:D)) --> (bool?(or A,C):(or B,D))
By the time the OR is visited, both the SELECTs have been visited and not
optimized and the OR itself hasn't been transformed so we do this transform in
the hopes that the new ORs will be optimized.
The transform is explicitly disabled for vector-selects until "codegen matures
to handle them better".

Fixed a crasher when the ConnectionFileDescriptor was used in a process with over FD_SETSIZE (1024) files open. It would corrupt the stack and cause the stack checker to assert and kill the program.
The final fix was to "#define _DARWIN_UNLIMITED_SELECT" at the top of the one and only file that uses select () in the LLDB codebase and then make an array of "fd_set" objects so they can handle more than 1024 file descriptors. The new code can handle as many file descriptors as a process can create.
