[PATCH] RISC-V: Support Zvabd version 0.9
This patch updates the binutils support for the RISC-V Zvabd (integer vector absolute difference) extension to its latest approved version, 0.9. The RISC-V Architecture Review Committee (ARC) revised the instruction variants and encodings, necessitating this update. The changes affect BFD, gas, and opcodes components, including modifications to ELF definitions, NEWS file, test cases, and opcode definitions.
