RISC-V: Add support for the Zvbb ISA extension
Zvbb is part of the vector crypto extensions.
This extension adds the following instructions:
- vandn.[vv,vx]
- vbrev.v
- vbrev8.v
- vrev8.v
- vclz.v
- vctz.v
- vcpop.v
- vrol.[vv,vx]
- vror.[vv,vx,vi]
- vwsll.[vv,vx,vi]
bfd/ChangeLog:
* elfxx-riscv.c (riscv_multi_subset_supports): Add instruction
class support for Zvbb.
(riscv_multi_subset_supports_ext): Likewise.
gas/ChangeLog:
* config/tc-riscv.c (validate_riscv_insn): Add 'l' as new format
string directive.
