Slightly clean up test-case:
$ cat pr100643.c
int foo()
{
int foo(void) __attribute__((target("avx")));
int foo(void) __attribute__((target("default")));
return 123;
}
$ g++ pr100643.c -c
pr100643.c:7:1: internal compiler error: in
ix86_mangle_function_version_assembler_name, at
config/i386/i386-features.c:2809

Where we ICE because the top-level function definition has
DECL_FUNCTION_VERSIONED (decl) set, but it does not contain "target" attribute.
@Jason: Is it really a valid test-case?
