Chris Lattner fedd9a5e1d put instructions into a map instead of a vector for quick lookup

Chris Lattner f38ce8f756 when parsing instructions remember information about the types taken and 
returned.

Chris Lattner bc7aabce12 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.

Chris Lattner 3ba60bf644 Parse significantly more of the instruction pattern, now collecting and 
verifying information about the operands.

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 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.
