Actually I rather suspect there is effectively a table in the CPU
indexed by the last 3 bits of the FLD* opcode... It would be
possible to implement this group of insns in QEMU with a single
helper function that took the index into the array, but since the
array seems to be causing weird compilation problems we might
as well stick with the lots-of-helpers approach, at which point
this is a sensible cleanup.
