52c3a1d654 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.

63392ea3ba Refactor the SROA visitors for partitioning an alloca and building 
partition use lists a bit. No functionality changed.

These visitors are actually visiting a tuple of a Use and an offset into
the alloca. However, we use the InstVisitor to handle the dispatch over
the users, and so the Use and Offset are stored in class member
variables and set just before each call to visit(). This is fairly
awkward and makes the functions a bit harder to read, but its the only
real option we have until InstVisitor can be rewritten to use variadic
templates.

However, this pattern shouldn't be followed on the helper member
functions where there is no interface constraint from the visitor. We
already were passing the instruction as a normal parameter rather than
use the Use to get at it, start passing the offset as well. This will
become more important in subsequent patches as the offset will in some
cases change while visiting a single instruction.

638e4c13cb The PMOVZXWD family of functions had patterns extends narrow vector types to wide vector types. 
It had patterns for zext-loading and extending. This commit adds patterns for loading a wide type, performing a bitcast,
and extending. This is an odd pattern, but it is commonly used when writing code with intrinsics.

c722ae7a2b Add alternative coalescing algorithm under a flag. 
The live range of an SSA value forms a sub-tree of the dominator tree.
That means the live ranges of two values overlap if and only if the def
of one value lies within the live range of the other.

This can be used to simplify the interference checking a bit: Visit each
def in the two registers about to be joined. Check for interference
against the value that is live in the other register at the def point
only. It is not necessary to scan the set of overlapping live ranges,
this interference check can be done while computing the value mapping
required for the final live range join.

The new algorithm is prepared to handle more complicated conflict
resolution - We can allow overlapping live ranges with different values
as long as the differing lanes are undef or unused in the other
register.

The implementation in this patch doesn't do that yet, it creates code
that is nearly identical to the old algorithm's, except:

- The new stripCopies() function sees through multiple copies while
  the old RegistersDefinedFromSameValue() only can handle one.

- There are a few rare cases where the new algorithm can erase an
  IMPLICIT_DEF instuction that RegistersDefinedFromSameValue() couldn't
  handle.

2131eb4887 Fix problem when using LiveRangeQuery with block entries. 
A value that is live in to a basic block should be returned by valueIn()
in LiveRangeQuery(getMBBStartIdx(MBB)), unless it is a PHI-def which
should be returned by valueDefined() instead.

Current code isn't using this functionality. Future code will.
