Alias/intrinsic policy on overlapped insns #128

Current spec requires intrinsics such as __rv_sadd64 (it is just int64 + int64), __rv_smmul (while it performs different asm insns), etc.
This raises the following questions:

  • If p-ext is presented, should assembler provide aliases (such as rv64/add64 as an alias of add)?
  • -- " --, should compiler provide zbpbo intrinsics with zbpbo names (e.g. __rv_rev)?
