eb79b545fc Soften the pattern-can-never-match error in TableGen into a warning. This pattern can be very useful in cases where you want to define a multiclass that covers both commutative and non-commutative operators (say, add and sub).

90fee07298 Refactor Record* by-ID comparator to Record.h
This is a generally useful utility; there's no reason to have it hidden
in CodeGenDAGPatterns.cpp.

Also, rename it to fit the other comparators in Record.h

34aadd6334 Replaced ReInitMCSubtargetInfo with InitMCProcessor.

the same information as InitMCSubtargetInfo instead of only setting
the feature bits.

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.

a6035773d8 Add TRI::getSubRegIndexLaneMask().
Sub-register lane masks are bitmasks that can be used to determine if
two sub-registers of a virtual register will overlap. For example, ARM's
ssub0 and ssub1 sub-register indices don't overlap each other, but both
overlap dsub0 and qsub0.

The lane masks will be accurate on most targets, but on targets that use
sub-register indexes in an irregular way, the masks may conservatively
report that two sub-register indices overlap when the eventually
allocated physregs don't.

Irregular register banks also mean that the bits in a lane mask can't be
mapped onto register units, but the concept is similar.
