one precious bit in SVP64 LDST-Immediate is being used up as
"Post-Increment" and it has to go. more than that, there are
circumstances where Post-Increment should be used with other
modes.

thus CSV files with post-increment for ld/st and fp-l/s
need an RFC.  also needed is implementations of FP LD/ST
with postinc, the fixedpoint ones already exist.
