6f94c802a2 Promote xform fns to be explicit nodes in result patterns, and clean off 
predicates since they will have already matched at this point.

57cae81b5e start building the instruction dest pattern correctly. Change the xform 
functions to preserve the Record for the xform instead of making it into a
function name.

a6d21c974c Implement a complete type inference system for dag patterns, based on the 
constraints defined in the DAG node definitions in the .td files.  This
allows us to infer (and check!) the types for all nodes in the current
ppc .td file.  For example, instead of:

Inst pattern EQV:       (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>))

we now fully infer:

Inst pattern EQV:       (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>))

from:  (set GPRC:$rT, (not (xor GPRC:$rA, GPRC:$rB)))

03637c7200 Keep names even when inlining. This allows us to realize that ADDI is: 
(set GPRC:i32:$rD, (add GPRC:i32:$rA, (imm)<<Predicate_immSExt16>>:$imm))

not:

(set GPRC:i32:$rD, (add GPRC:i32:$rA, (imm)<<Predicate_immSExt16>>))

(we keep the ":$imm")

65c98b6441 Initial cut of the dag isel generator. This is still very much a work in 
progress.  It correctly parses instructions and pattern fragments and glues
together pattern fragments into instructions.

The only code it generates currently is some boilerplate code for things
like the EntryNode.

46a7fdeb66 Implement PR614: 
These changes modify the makefiles so that the output of flex and bison are
placed in the SRC directory, not the OBJ directory. It is intended that they
be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or
.l file you *must* also commit the generated .cpp and .h files.
