77511d5a11 PGO: preserve branch-weight metadata when simplifying Switch 
Hanlde the case when we split the default edge if the default target has "icmp"
and unconditinal branch.

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.

c0b9726fe7 Make sure there is enough room for RA. getStackSize needs to be cleaned up but 
we will do that when we implement the full save/restore.
