rs6000: Fix fsel pattern (PR79211)
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.
PR target/79211
* config/rs6000/rs6000.md (*fsel<SFDF:mode><SFDF2:mode>4): Use
gpc_reg_operand instead of fpr_reg_operand.
