Anton Korobeynikov 928eb49cae Make processor FUs unique for given itinerary. This extends the limit of 32 
FU per CPU arch to 32 per intinerary allowing precise modelling of quite
complex pipelines in the future.

// VFP and NEON shares the same register file. This means that every VFP
// instruction should wait for full completion of the consecutive NEON
// instruction and vice-versa. We model this behavior with two artificial FUs:
// DRegsVFP and DRegsVFP.
//
// Every VFP instruction:
// - Acquires DRegsVFP resource for 1 cycle
// - Reserves DRegsN resource for the whole duration (including time to
// register file writeback!).
// Every NEON instruction does the same but with FUs swapped.
//
// Since the reserved FU cannot be acquired this models precisly "cross-domain"
// stalls.
// VFP
// Issue through integer pipeline, and execute in NEON unit.
