RISC-V: Add macro-only operands to validate_riscv_insn
Although they are not (and should not be) reachable, following macro-only
operands are parsed in the `validate_riscv_insn' function and ignored.
That function also notes that they are macro-only.
- "A"
- "B"
- "I"
Following this convention, this commit adds three remaining macro-only
operands to this function. By doing this, we could instead choose to reject
those operands from appearing in regular instructions later.
- "c" (used by call, tail and jump macros)
- "VM" (used by vmsge.vx and vmsgeu.vx macros)
- "VT" (likewise)
gas/ChangeLog:
* config/tc-riscv.c (validate_riscv_insn): Add "c", "VM" and "VT"
macro-only operand types.
