Hi!
The assertion doesn't allow IFN_COND_MIN/IFN_COND_MAX, which are
commutative conditional binary operations like ADD/MUL/AND/IOR/XOR,
and can be handled just fine.
In particular, we emit
vminpd %zmm3, %zmm5, %zmm0{%k2}
vminpd %zmm0, %zmm3, %zmm5{%k1}
and
vmaxpd %zmm3, %zmm5, %zmm0{%k2}
vmaxpd %zmm0, %zmm3, %zmm5{%k1}
in the vectorized loops of the first and second subroutine.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk and
14.1?
