a28aec1da7 teach the type inference code how to infer types for instructions and node
xforms.  Run type inference on result patterns, so we always have fully typed
results (and to catch errors in .td files).

b0276200e6 start building the instruction dest pattern correctly. Change the xform
functions to preserve the Record for the xform instead of making it into a

the scheduler from causing problems by moving a copyfromreg for an argument
to after a select_cc node (now it can, and bad things won't happen).
