Greg Clayton 4570d3eba0 Massive test suite cleanup to stop everyone from manually having to compute "mydir" inside each test case. 
This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.

Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

Greg Clayton 7051231709 <rdar://problem/11358639> 
Switch over to the "*-apple-macosx" for desktop and "*-apple-ios" for iOS triples.

Also make the selection process for auto selecting platforms based off of an arch much better.

Caroline Tice 3ac6711aec Add the infrastructure to test instruction emulations automatically. 
The idea is that the instruction to be emulated is actually executed
on the hardware to be emulated, with the before and after state of the
hardware being captured and 'freeze-dried' into .dat files.  The
emulation testing code then loads the before & after state from the
.dat file, emulates the instruction using the before state, and
compares the resulting state to the 'after' state.  If they match, the
emulation is accurate, otherwise there is a problem.

The final format of the .dat files needs a bit more work; the plan is
to generalize them a bit and to convert the plain values to key-value pairs. 
But I wanted to get this first pass committed.

This commit adds arm instruction emulation testing to the testsuite, along with
many initial .dat files.

It also fixes a bug in the llvm disassembler, where 32-bit thumb opcodes
were getting their upper & lower 16-bits reversed.

There is a new Instruction sub-class, that is intended to be loaded
from a .dat file rather than read from an executable.  There is also a
new EmulationStateARM class, for handling the before & after states.
EmulationStates for other architetures can be added later when we
emulate their instructions.
