9b43f33620 Change all self assignments X=X to (void)X, so that we can turn on a 
new gcc warning that complains on self-assignments and
self-initializations.

a6cd2d821a Rename NeedsSetToChangeDiffSize to HasAggressiveSymbolFolding which is a much 
better name and matches what is used in the MachO writer.

6bdb49ded8 Don't relax org or align. They change size as the relaxation happens, but they 
are not actually relaxed. For example, a section with only alignments will never
needs relaxation.

plenty left though!), in particular for multiplication.

98d93c5294 Layout one section until no relaxations are done and then move to the next 
section.

This helps because in practice sections form a dag with debug sections pointing
to text sections. Finishing up the text sections first makes the debug section
relaxation trivial.

3e5fbd74ed rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

4c278f82c8 Use IntEqClasses to compute connected components of live intervals.

Jakob Stoklund Olesen
baee655c5e Add ADT/IntEqClasses.h as a light-weight implementation of EquivalenceClasses.h. 
This implementation already exists as ConnectedVNInfoEqClasses in
LiveInterval.cpp, and it seems to be generally useful to have a light-weight way
of forming equivalence classes of small integers.

IntEqClasses doesn't allow enumeration of the elements in a class.

a436cbe4bf Add a new convenience pass for testing InstructionSimplify. Previously 
it could only be tested indirectly, via instcombine, gvn or some other
pass that makes use of InstructionSimplify, which means that testcases
had to be carefully contrived to dance around any other transformations
that that pass did.

3fff1fd49b During local stack slot allocation, the materializeFrameBaseRegister function 
may be called. If the entry block is empty, the insertion point iterator will be
the "end()" value. Calling ->getParent() on it (among others) causes problems.

Modify materializeFrameBaseRegister to take the machine basic block and insert
the frame base register at the beginning of that block. (It's very similar to
what the code does all ready. The only difference is that it will always insert
at the beginning of the entry block instead of after a previous materialization
of the frame base register. I doubt that that matters here.)

54912ed921 It is allowed to call IntervalMap::const_iterator::advanceTo() with a key that 
moves the iterator to end(), and it is valid to call it on end().

That means it is valid to call advanceTo() with any monotonic key sequence.
