6cba50cbb4 Replaced ReInitMCSubtargetInfo with InitMCProcessor. 
Now where we used to call ReInitMCSubtargetInfo, we actually recompute
the same information as InitMCSubtargetInfo instead of only setting
the feature bits.

82c85585f9 Use vld1 / vst2 for unaligned v2f64 load / store. e.g. Use vld1.16 for 2-byte 
aligned address. Based on patch by David Peixotto.

Also use vld1.64 / vst1.64 with 128-bit alignment to take advantage of alignment
hints. rdar://12090772, rdar://12238782

b761721812 Merge into undefined lanes under -new-coalescer. 
Add LIS::pruneValue() and extendToIndices(). These two functions are
used by the register coalescer when merging two live ranges requires
more than a trivial value mapping as supported by LiveInterval::join().

The pruneValue() function can remove the part of a value number that is
going to conflict in join(). Afterwards, extendToIndices can restore the
live range, using any new dominating value numbers and updating the SSA
form.

Use this complex value mapping to support merging a register into a
vector lane that has a conflicting value, but the clobbered lane is
undef.

b004b398e9 Stop adding <imp-def> operands when expanding REG_SEQUENCE. 
These extra operands are not needed by register allocators using
VirtRegRewriter, and RAFast don't need them any longer.

By omitting the <imp-def> operands, it becomes possible for the new
register coalescer to track which lanes are valid and which are undef.

ef09f46517 TableGen subtarget emitter. Generate data tables for the new machine model. 
Map the CodeGenSchedule object model onto data tables. The structure
of the data tables is defined in MC, so for convenience we include
MCSchedule.h. The alternative is maintaining a redundant copy of the
table structure definitions. Mapping the object model onto data tables
is sufficiently complicated that it should not be interleaved with
emitting source code. This avoids major problem with the backend for
itinerary generation.
