    [committed] Remove compromised sh test
    
    Surya's recent patch to IRA improves the code for sh/pr54602-1.c slightly.
    Specifically it's able to eliminate a save/restore in the prologue/epilogue and
    a bit of register shuffling.
    
    As a result there literally aren't any insns that can be used to fill the delay
    slot of the return, so a nop gets emitted and the test fails.
    
    Given there literally aren't any insns to move into the delay slot, the best
    course of action is to just drop the test.

            * gcc.target/sh/pr54602-1.c: Delete test.
