s390x/tcg: add instruction flags for floating point instructions
These flags allow us to later on detect if a DATA program interrupt
is to be injected, and which DXC (1,2,3) is to be used.
Interestingly, some support FP instructions are considered as HFP
instructions (I assume simply because they were available very early).
