cmd/compile: stop storing TFIELD types in Node.Type

Browse source 
Currently, the only use for this is on the Left side of OKEY nodes
within struct literals.  esc and fmt only care so they can recognize
that the ONAME nodes are actually field names, which need special
handling.

sinit additionally needs to know the field's offset within the struct,
which we can provide via Xoffset.

Passes toolstash/buildall.
