    [PR99531] Modify pseudo class cost calculation when processing move
involving the pseudo and a hard register

    Pseudo class calculated on the 1st iteration should not have a
    special treatment in cost calculation when processing move involving
    the pseudo and a hard register.

    gcc/ChangeLog:

            PR target/99531
            * ira-costs.c (record_operand_costs): Do not take pseudo class
            calculated on the 1st iteration into account when processing move
            involving the pseudo and a hard register.

    gcc/testsuite/ChangeLog:

            PR target/99531
            * gcc.target/i386/pr99531.c: New test.
