bug #672: shorten pospopcount further

by setting VL=MVL=8 the sv.popcntd/sw=8 will wipe out the unused destinations
to zeros, so no need to clear them manually. loses one additional instruction

bug #672: pospopcount working with large arrays

pospopcount is supposed to be able to handle long arrays of data,
but it turns out that sv.lbzu/pi/dw=8 was calculating an EA in 8-bit,
meaning that it wrapped around to a zero memory address.
now this is resolved the code which has been made shorter actually works

bug #672: pospopcount using sv.lbzu/pi/dw=8 error

COMPLEX! this turns out to be a spec violation where RA (EA)
*must* be treated as 64-bit *NOT* have its width overridden
just because destination elwidth is set to 8-bit.
* source elwidth is supposed to apply to STORE
* dest elwidth is supposed to apply to LOAD
but those are MEMORY DATA not memory ADDRESSes they are
supposed to apply to.

TODO, most likely LDST_IDX needs fixing (RB may also need
an elwidth cancellation/override, have to check the spec)

there is a lot going on here, this is pushing the boundaries of
what ISAcaller can do (or hasnt been asked to do... until now)
* gbbd (gather bits and bytes double) had to be added
* sw=8,dw=64 had to be fixed (XLEN is actually 64 there
  but source elements have to be ZERO-EXTENDED...)
* a bug in sv.addi/sw=8 was found

* some changes to setvl have to be made/written (!)
* sv.bc in CTR-reduction mode needs to potentially be fixed
  or at least properly examined

fix elwidth overrides when sw=8
the way that XLEN works is it must be MAX(sw,dw) which is not what
