[PATCH v3 0/3] RISC-V: Add stub support for existing extensions

[Tsukasa OI via Gcc-patches]

PATCH v1:
<https://gcc.gnu.org/pipermail/gcc-patches/2023-August/627220.html>
PATCH v2:
<https://gcc.gnu.org/pipermail/gcc-patches/2023-August/627295.html>


Changes: v1 -> v2 (only in PATCH 3/3)
======================================

Removed: 'Zvkn' -> 'Zvknha' implication (not to cause test failure)
Added:   'Zfa' -> 'F' implication (just I forgot to add in PATCH v1)


Changes: v2 -> v3 (only in PATCH 3/3)
======================================

Changed: 'Zcmt' -> 'Zcicsr' to
         'Zcmt' ->  'Zicsr' (fix typo)
Rebased against commit 17c22f466162
                ("RISC-V: Minimal support for ZC* extensions.").
            and commit 30699b999e94
                ("[PATCH v10] RISC-V: Add support for the Zfa extension").
Slightly modified the commit message, reflecting the background.

As a rebase result, PATCH 3/3 got nearly empty (except a test case).


Thanks,
Tsukasa
