[Patch, gcc, testsuite] Use long enums for case foldconst-3.c for target ARM EABI.

[Terry Guo]

Hello,

This patch aims to disable short enums for arm eabi otherwise the case will
fail to be compiled due to "width of 'code' exceeds its type". Is it OK to
trunk?

BR,
Terry

          * gcc.dg/tree-ssa/foldconst-3.c: Use -fno-short-enums 
        for ARM EABI target.
