7a45903bf4 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.

62b83b62f3 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.

f1b4eafbfe 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.

2a6899c539 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.

43ff68ded0 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.

976ef86689 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.)

5049ee5b11 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.
