sv.c - add BODYLESS_NV fast code to sv_setXv functions

For "BODYLESS" IVs and NVs, type up/downgrades can be easily done
without having to call sv_upgrade. (Which will also not convert a
BODYLESS NV back down to an IV, even when it is harmless to do so.)

This commit adds "BODYLESS" handling to sv_setiv and sv_setnv, which
previously lacked it, and "BODYLESS_NV" handling to sv_setsv_flags,
which previously only special-cased "BODYLESS_IV"s.

The BODYLESS_IV code in sv_setsv_flags previously did not preserve
flags such as SVs_TEMP or SVs_PADTMP, which seemed like a potential
latent bug. (The new BODYLESS_NV code *has* to preserve SVs_TEMP in
order for all tests in t/lib/warnings to continue to pass.) Rather
than clearing all flags, this commit instead does a SvOK_off(dsv)
for both BODYLESS_IV and BODYLESS_NV cases.
