zce must imply zcf but this rule was corrupted after
refactoring in 9e12010b5e724277ea. This may be observed
ater generating an .s file from any source code file with
-mriscv-attribute -march=rv32if_zce -mabi=ilp32 -S
options. A full march will be presented in arch attribute:
rv32i2p1_f2p2_zicsr2p0_zca1p0_zcb1p0_zce1p0_zcmp1p0_zcmt1p0
As you see, zcf is not presented here though f_zce pair is
passed in -march. According to The RISC-V Instruction
Set Manual:
Specifying Zce on RV32 with F includes Zca, Zcb, Zcmp,
Zcmt and Zcf.
