Document the named field syntax that we want to implement for the decodetree script. This allows a field to be defined in terms of some other field that the instruction pattern has already set, for example:%sz_imm 10:3 sz:3 !function=expand_sz_imm to allow a function to be passed both an immediate field from the instruction and also a sz value which might have been specified by the instruction pattern directly (sz=1, etc) rather than being a simple field within the instruction. Note that the restriction on not having the format referring to the pattern and the pattern referring to the format simultaneously is a restriction of the decoder generator rather than inherently being a silly thing to do.
