RISC-V: Prohibit the 'Zcf' extension on RV64
As per:
<https://github.com/riscv/riscv-code-size-reduction/issues/221>,
the 'Zcf' extension does not exist on RV64. This is reflected on the
version 1.0.4-1 of the code size reduction specification:
<https://github.com/riscv/riscv-code-size-reduction/releases/tag/v1.0.4-1>.
This commit prohibits the combination: RV64 (or any ISA with XLEN > 32)
and the 'Zcf' extension.
bfd/ChangeLog:
* elfxx-riscv.c (riscv_parse_check_conflicts): Prohibit
combination of RV64 and 'Zcf'.
gas/ChangeLog:
* testsuite/gas/riscv/march-fail-rv64i_zcf.d: New test.
* testsuite/gas/riscv/march-fail-rv64i_zcf.l: Likewise.
