Use rvec4 for listed force buffer
To allow aligned 4-wide SIMD force reduction, changed the force
buffer passed to ifunc from rvec to rvec4.
Because the listed and normal force buffers now have a different
format, the listed force buffer reduction over threads also needs
to reduce the buffer of thread 0 and is thus now also used without
OpenMP threading. This extra cost is more than outweighed by the
faster listed force updates.
The current force updates in bonded.cpp will be replaced by SIMD
transposeScatter in a separate commit.
