Jim Grosbach e9cc901814 Refact ARM Thumb1 tMOVr instruction family. 
Merge the tMOVr, tMOVgpr2tgpr, tMOVtgpr2gpr, and tMOVgpr2gpr instructions
into tMOVr. There's no need to keep them separate. Giving the tMOVr
instruction the proper GPR register class for its operands is sufficient
to give the register allocator enough information to do the right thing
directly.

Bill Wendling b403f0c4ed Add target a target hook to get the register number used by the compact unwind 
encoding for the registers it knows about. Return -1 if it can't handle that
register.

Jim Grosbach b98ab91e39 Thumb1 register to register MOV instruction is predicable. 
Fix a FIXME and allow predication (in Thumb2) for the T1 register to
register MOV instructions. This allows some better codegen with
if-conversion (as seen in the test updates), plus it lays the groundwork
for pseudo-izing the tMOVCC instructions.

Tobias Grosser de68cc91cf ScheduleOpt: Use band forest to get the schedules 
isl introduced a new representation for the schedules it calculates. The new
representation uses a forest of bands and is closer to the structure of the
data as the old interface. Switch to the new interface, as it is nicer to use
and as the old interface will soon be removed from isl.

WARNING: This commit needs a version of isl that is more recent that the one
         included in CLooG. See:

Jim Grosbach 353da73186 Pseudo-ize the t2LDMIA_RET instruction. 
It's just a t2LDMIA_UPD instruction with extra codegen properties, so it
doesn't need the encoding information. As a side-benefit, we now correctly
recognize for instruction printing as a 'pop' instruction.

Chandler Carruth c91f09d73a Fix an obvious typo in an attribute's diagnostics. 
Patch by Caitlin Sadowski.

Unfortunately, this attribute doesn't seem to have a single test. It is
only mentioned in comments in one test, and as a string literal in
a copy of some Clang code checked in as a test for the Indexer. =[ It
dates from 2009 r74280 as part of OpenCL 1.0.
