    [PR98722] LRA: Check that target has no 3-op add insn to transform 2 pl=
us
expression.

    Patch cf2ac1c30af0fa783c8d72e527904dda5d8cc330 for solving PR97969 was
    assumed for targets with absent 3-op add insn.  But the original patch =
did
    not check this.  This patch adds the check.

    gcc/ChangeLog:

            PR rtl-optimization/98722
            * lra-eliminations.c (eliminate_regs_in_insn): Check that target
            has no 3-op add insn to transform insns containing two pluses.

    gcc/testsuite/ChangeLog:

            PR rtl-optimization/98722
            * g++.target/s390/pr98722.C: New.
