[PATCH, testsuite] Fix g++.dg/debug/ra1.C

[Yufeng Zhang]

Hi,

g++.dg/debug/ra1.C fails on arm-none-eabi with the following message 
because enum types in arm eabi are represented by the smallest integral 
type:

warning: width of 'tree_base::code' exceeds its type [enabled by default]

This patch updates the test by changing the width of the 'code' bitfield 
from 16 to 8.

The patch passes make check-g++ RUNTESTFLAGS="debug.exp=ra1.C" on 
arm-none-eabi and x86_64.

OK for the mainline?

Thanks,
Yufeng

        * g++.dg/debug/ra1.C (struct tree_base): Change the width of
        the 'code' bitfield from 16 to 8.
