  From: Jiawei <jiawei@iscas.ac.cn>

Support 'TARGET_ZFINX' with float instruction pattern and builtin function.
Reuse 'TARGET_HADR_FLOAT',  'TARGET_DOUBLE_FLOAT' and 'TARGET_ZHINX' patterns.

gcc/ChangeLog:

        * config/riscv/iterators.md (TARGET_ZFINX):New target.
	(TARGET_ZDINX): Ditto.
	(TARGET_ZHINX): Ditto.
        * config/riscv/riscv-builtins.cc (AVAIL): Ditto.
        (riscv_atomic_assign_expand_fenv): Ditto.
        * config/riscv/riscv-c.cc (riscv_cpu_cpp_builtins): Ditto.
        * config/riscv/riscv.md: Ditto.
