* z_lifemeter OK
There were a few versions that matched, so the duplicate `ddfactor`
might be fake. The `if (interfaceCtx)` at the start seems to be required.
I think `sHeartsPrimFactors[0]` vs `sHeartsDDPrimFactors[ddtype]` is
real, because the asm loads `sHeartsDDPrimFactors` for each access,
while it only loads `sHeartsPrimFactors` once. It could have something
to do with `reduceixa` in uopt.
* Make vars function-static
* Fix names
