[PR98722] LRA: Check that target has no 3-op add insn to transform 2 plus 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.
