* gdb.arch/i386-prologue.c (stack_align_ecx): Renamed from stack_align.

        (stack_align_edx): New function.
        (stack_align_eax): New function.
        (main): Add calls to stack_align_edx and stack_align_eax.
        * gdb.arch/i386-prologue.exp: Replace stack_align with stack_align_ecx.
        Add testing for the cases where the register used during a stack
        realignment is edx. Same for eax.
