[PATCH] Use HOST_WIDE_INT_C some more in the i386 backend

[Jakub Jelinek]

Hi!

I found a couple of spots where we can use the HOST_WIDE_INT_C macro.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

        * config/i386/i386.c (ix86_compute_frame_layout, ix86_expand_prologue,
        ix86_expand_split_stack_prologue): Use HOST_WIDE_INT_C macro.
        (ix86_split_to_parts): Likewise.  Fix up formatting.
