Jakob Stoklund Olesen 0bb3dd78c4 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.

Jakob Stoklund Olesen af50f17df4 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.

Andrew Trick 9ef0882b72 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.

Anna Zaks 4278234360 [analyzer] Teach the analyzer about implicit initialization of statics 
in ObjCMethods.

Extend FunctionTextRegion to represent ObjC methods as well as
functions. Note, it is not clear what type ObjCMethod region should
return. Since the type of the FunctionText region is not currently used,
defer solving this issue.

Jordan Rose 67e887c9b5 -Warc-retain-cycles: look through [^{...} copy] and Block_copy(^{...}) 
Retain cycles happen in the case where a block is persisted past its
life on the stack, and the way that occurs is by copying the block.
We should thus look through any explicit copies we see.

Note that Block_copy is actually a type-safe wrapper for _Block_copy,
which does all the real work.
