    IRA: Revert 11b8091fb to fix PR 93221

    A previous change to simplify LRA introduced in 11b809 (From-SVN: r279550)
    disabled hard register splitting for -O0. This causes a problem on aarch64
in
    cases where parameters are passed in multiple registers (in the bug report
an OI
    passed in 2 V4SI registers). This is mandated by the AAPCS.
