[Issue]
When I use gcc-4.8.1 to cross-compile below C program for PPC target with
e500v2 core, following ICE appears, same C file can be compiled correctly for
targets with e500mc/e5500/x86 core.

More observation: during my trial, when the array size is equal to 4096 or
smaller than 4096, compile can pass, otherwise build will fail.
