[AMDGPU] Allow any value in unused src0 field in v_nop
Summary:
The LLVM disassembler assumes that the unused src0 operand of v_nop is
zero. Other tools can put another value in that field, which is still
valid. This commit fixes the LLVM disassembler to recognize such an
encoding as v_nop, in the same way as we already do for s_getpc.
