The fsel define_insn uses fpr_reg_operand for its predicates. This
won't work because passes can put a hard register in the operands: in
the testcase, combine likes to forward the parameter registers to what
then is still an smin, and then split1 uses "*s<minmax><mode>3_fpr"
(which has gpc_reg_operand). And then we have a GPR in the operand,
which does not match fpr_reg_operand.
It seems to me the predicates should be gpc_reg_operand here as well.
This patch changes that.
