Move Zicond md files ahead of SFB to recognize Zicond first.
Take the following case for example.
CFLAGS: -mtune=sifive-7-series -march=rv64gc_zicond -mabi=lp64d
long primitiveSemantics_00(long a, long b) { return a == 0 ? 0 : b; }
before patch:
primitiveSemantics_00:
bne a0,zero,1f
Personally I don't like to play with the pattern order to tweak the
code gen since it kinda introduces implicit relation/rule here, but I
guess the only way to prevent that is to duplicate the pattern for SFB
again, which is not an ideal solution...
Anyway, it's obviously a better code gen, so LGT
