[v12,0/7] riscv: set vstart_eq_zero on vector insns

Message

Hi,

In this new version we reworked the commit message of patch 4, as
suggested by Richard, since the solution we went for in patch 3
trivialized the removal of 'brcond' since we're doing an early exit if
vstart >= vl.

No other changes made. Patches based on master.

All patches acked.

Changes from v11:
- patch 4:
  - commit msg rewritten taking VSTART_CHECK_EARLY_EXIT() into
    consideration
- v11 link: https://lore.kernel.org/qemu-riscv/[e-mail]/
