t2LDREX/t2STREX instructions.  Add two test cases.

15a3ea0628 Emit less labels for debug info and stop emitting .loc directives for DBG_VALUEs.
The .dot directives don't need labels, that is a leftover from when we created
line number info manually.

Instructions following a DBG_VALUE can share its label since the DBG_VALUE
doesn't produce any code.

1090d7711b The ARM disassembler was confused with the 16-bit tSTMIA instruction.
According to A8.6.189 STM/STMIA/STMEA (Encoding T1), there's only tSTMIA_UPD available.
Ignore tSTMIA for the decoder emitter and add a test case for that.

These two are test cases which should result in 'invalid instruction encoding' from running llvm-mc -disassemble.

e6d69e7dbe ADR was added with the wrong encoding for inst{24-21}, and the ARM decoder was fooled.
Set the encoding bits to {0,?,?,0}, not 0.  Plus delegate the disassembly of ADR to
the more generic ADDri/SUBri instructions, and add a test case for that.

d700617193 Nasty bug in ARMBaseInstrInfo::produceSameValue(). The MachineConstantPoolEntry
entries being compared may not be ARMConstantPoolValue. Without checking
whether they are ARMConstantPoolValue first, and if the stars and moons
are aligned properly, the equality test may return true (when the first few
words of two Constants' values happen to be identical) and very bad things can
happen.
