[PATCH 0/5] RISC-V: Add Ratified Cache Management Operation ISA Extensions (with paren)

[Tsukasa OI <research_trasio@irq.a4lg.com>]

This patchset is a modified version of:
<https://sourceware.org/pipermail/binutils/2021-December/118909.html>

GitHub:
<https://github.com/a4lg/binutils-gdb/tree/riscv-CMOs> (original; 2021-12-16, rebased)
<https://github.com/a4lg/binutils-gdb/tree/riscv-CMOs-with-paren> (new: 2022-02-09)


There seems a discussion to change operand of cbo.* instructions on:
<https://github.com/riscv/riscv-CMOs/issues/47>.

I have a little preference for old one but it's not bad to have both
options (as complete patchsets).

Note that however, the original patchset is *NOT OUTDATED* yet.
It implements Zicbom/Zicboz instruction like:

    cbo.zero    a0

This new patchset implements Zicbom/Zicboz instructions like:

    cbo.zero    (a0)
    cbo.zero    0(a0)    # only zero is allowed

Actually, my first attempt to implement cbo.* instructions used the same
format as *new* patchset (I modified before submitting the first
patchset for compliance to the specification document).

This version requires extra checking (0(a0) actually allows
EXPRESSION_RESULTS_IN_ZERO(a0)) so I added a few extra tests.
It will also reject operand format in older patchset.

Old patchset and new patchset are mutually exclusive and should follow
the conclusion of the discussion above.

Thanks,
Tsukasa
