[testsuite] XFAIL Warray-bounds-4.c on SPARC and Visium

[Eric Botcazou]

On these platforms, one of the instances of the constructor generated in 
test_strcpy_bounds_memarray_range is put into the constant pool so the strlen 
pass cannot do its magic.

Tested on visium-elf, SPARC64 and x86-64/Linux, applied on the mainline.

        * c-c++-common/Warray-bounds-4.c (test_strcpy_bounds_memarray_range): 
        XFAIL last test on SPARC and Visium.
