PHIOPT: move factor_out_conditional_operation over to use gimple_match_op

To start working on more with expressions with more than one operand, converting
over to use gimple_match_op is needed.
The added side-effect here is factor_out_conditional_operation can now support
builtins/internal calls that has one operand without any extra code added.

Note on the changed testcases:
* pr87007-5.c: the test was testing testing for avoiding partial register stalls
for the sqrt and making sure there is only one zero of the register before the
branch, the phiopt would now merge the sqrt's so disable phiopt.

Bootstrapped and tested on x86_64-linux-gnu with no regressions.

gcc/ChangeLog:

	* gimple-match-exports.cc (gimple_match_op::operands_occurs_in_abnormal_phi):
	New function.
	* gimple-match.h (gimple_match_op): Add operands_occurs_in_abnormal_phi.
	* tree-ssa-phiopt.cc (factor_out_conditional_operation): Use gimple_match_op
	instead of manually extracting from/creating the gimple.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr87007-5.c: Disable phi-opt.
