af468d8d5a add TableGen support to create relationship maps between instructions 
Relationship maps are represented as InstrMapping records which are parsed by
TableGen and the information is used to construct mapping tables to represent
appropriate relations between instructions. These tables are emitted into
XXXGenInstrInfo.inc file along with the functions to query them.

Patch by Jyotsna Verma <jverma@codeaurora.org>.

48d2376b89 lit: Remove support for XTARGET. 
- The XTARGET feature (inherited from old DG tests) was just confusing (and
   barely ever used). The same effect can now be achieved with a combination of
   the more useful REQUIRES and XFAIL.

a77399599d Attributes Rewrite 
Convert the internal representation of the Attributes class into a pointer to an
opaque object that's uniqued by and stored in the LLVMContext object. The
Attributes class then becomes a thin wrapper around this opaque
object. Eventually, the internal representation will be expanded to include
attributes that represent code generation options, etc.

a6a1c05042 tblgen: Mechanically move dynamic_cast<> to dyn_cast<>. 
Some of these dyn_cast<>'s would be better phrased as isa<> or cast<>.
That will happen in a future patch.

There are also two dyn_cast_or_null<>'s slipped in instead of
dyn_cast<>'s, since they were causing crashes with just dyn_cast<>.

f8b271827e tblgen: Replace uses of dynamic_cast<XXXRecTy> with dyn_cast<>. 
This is a mechanical change of dynamic_cast<> to dyn_cast<>. A number of
these uses are actually more like isa<> or cast<>, and will be changed
to the semanticaly appropriate one in a future patch.

d6d5b63b3b Added instregex support to TableGen subtarget emitter. 
This allows the processor-specific machine model to override selected
base opcodes without any fanciness.
e.g. InstRW<[CoreXWriteVANDP], (instregex "VANDP")>.

00263532fa TableGen subtarget emitter, nearly first class support for SchedAlias. 
A processor can now arbitrarily alias one SchedWrite onto
another. Only the SchedAlias definition need be within the processor
model. The aliased SchedWrite may be a SchedVariant, WriteSequence, or
transitively refer to another alias.

5e80eb4c86 [ms-inline asm] Add the convertToMapAndConstraints() function that is used to 
map constraints and MCInst operands to inline asm operands.  This replaces the
getMCInstOperandNum() function.

The logic to determine the constraints are not in place, so we still default to
a register constraint (i.e., "r"). Also, we no longer build the MCInst but
rather return just the opcode to get the MCInstrDesc.

eedf4ffbcb 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
