Chris Lattner d7d31f3b06 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)))

Chris Lattner 399f59f643 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")

Chris Lattner d2a5b366f5 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.
