a68a4fdf37 r120333 changed the opcode for the Thumb1 stuff from ARM::tMOVr to
ARM::tMOVgpr2gpr. But this check didn't change. As a result, we were getting
misaligned references to the jump table from an ADR instruction.

There is a test case, but unfortunately it's sensitive to random code changes.

dfe3b6d2a9 Check that the register is live-in to the loop header before inserting copies in
the loop predecessors.

The register can be live-out from a predecessor without being live-in to the
loop header if there is a critical edge from the predecessor.

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.

175fb36f10 Thumb's forced-PC-alignment requirement applies to the _total_ displacement, not just to the fragment relative
portion.  While the fragment boundary is usually already aligned, it is possible for it not to be, which 
would lead to a non-aligned final displacement.

2f3a4aa550 Allow missing kill flags on an untied operand of a two-address instruction when
the operand uses the same register as a tied operand:

  %r1 = add %r1, %r1

If add were a three-address instruction, kill flags would be required on at
least one of the uses. Since it is a two-address instruction, the tied use
operand must not have a kill flag.

This change makes the kill flag on the untied use operand optional.
