From: Matheus Ferst <matheus.ferst@eldorado.org.br>

In our "PowerISA Vector/VSX instruction batch" patch series, rth noted[1]
that helpers that only access vector registers should be declared with
DEF_HELPER_FLAGS_* and TCG_CALL_NO_RWG. We fixed helpers in that series,
but there are older helpers that could use the same optimization.

Guided by the presence of env as the first argument, in patches 1~4 we
change helpers that do not have access to the cpu_env pointer to modify
any globals. Then, we change other helpers that receive cpu_env but do
not use it and apply the same fix, taking the opportunity to move them
to decodetree.

Patches without review: 06.

v2:
 - darn32/darn64 helpers declared with TCG_CALL_NO_RWG_SE;
 - xscvspdpn implemented with helper_todouble, dropped helper_XSCVSPDPN;
 - vmsumuhs and vmsumshs helpers declared with TCG_CALL_NO_RWG;
 - Link to v1: https://lists.gnu.org/archive/html/qemu-ppc/2022-05/msg00287.html
