[PATCH 1/1] RISC-V: Imply 'Zicsr' from 'Zcmt'

[Tsukasa OI via Gcc-patches]

From: Tsukasa OI <research_tra...@irq.a4lg.com>

As the specification states, the 'Zcmt' extension depends on the 'Zca' and
'Zicsr' extensions.  This commit reflects this implication.

gcc/ChangeLog:

        * common/config/riscv/riscv-common.cc
        (riscv_implied_info): Add implication from 'Zcmt' to 'Zicsr'.
