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)))

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")

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.
