985dab611d Rename sat_shift operand to shift_imm, in preparation for using it for other 
instructions besides saturate instructions.  No functional changes.

78345b1dfe Cleaned up the for-disassembly-only entries in the arm instruction table so that 
the memory barrier variants (other than 'SY' full system domain read and write)
are treated as one instruction with option operand.

0650cceb38 Add a separate ARM instruction format for Saturate instructions. 
(I discovered 2 more copies of the ARM instruction format list, bringing the
total to 4!!  Two of them were already out of sync.  I haven't yet gotten into
the disassembler enough to know the best way to fix this, but something needs
to be done.)  Add support for encoding these instructions.

6d53fded19 Fix eabi calling convention when a 64 bit value shadows r3. 
Without this what was happening was:

* R3 is not marked as "used"
* ARM backend thinks it has to save it to the stack because of vaarg
* Offset computation correctly ignores it
* Offsets are wrong

ee46b1653d Change the logic which interprets output on stderr as an error so that 
it doesn't modify the exit code or the stdout contents, and so that it
doesn't clutter the output with "Command has output on stderr!".

53385ca642 tests: Add an 'llvm-lit' tool (script), which gets generated as part of the 
build and has the object build directory baked into it. This allows 'llvm-lit'
to properly find the information needed to run the test suite in all cases,
without requiring the user to have LLVM or 'lit' available in their PATH, for
example.

f70b028327 Add a "Compare" flag to the target instruction descriptor. This will be used 
later to identify and possibly remove superfluous compare instructions -- those
that are testing for and setting a status flag that should already be set.

1718345a30 Many Thumb2 instructions can reference the full ARM register set (i.e., 
have 4 bits per register in the operand encoding), but have undefined
behavior when the operand value is 13 or 15 (SP and PC, respectively).
The trivial coalescer in linear scan sometimes will merge a copy from
SP into a subsequent instruction which uses the copy, and if that
instruction cannot legally reference SP, we get bad code such as:
  mls r0,r9,r0,sp
instead of:
  mov r2, sp
  mls r0, r9, r0, r2

This patch adds a new register class for use by Thumb2 that excludes
the problematic registers (SP and PC) and is used instead of GPR
for those operands which cannot legally reference PC or SP. The
trivial coalescer explicitly requires that the register class
of the destination for the COPY instruction contain the source
register for the COPY to be considered for coalescing. This prevents
errant instructions like that above.
