Since http://gcc.gnu.org/ml/gcc-patches/2013-05/msg01475.html introduced
a warning for bit field types with width greater than the contained enum
width pr54684.C has failed for arm*-*-* due to the extra diagnostic
emitted. This patch disables short-enums in the test case.

builtin folding fails to update SSA operands properly.
Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.
