Fix build for LLVM >= r74640 Some LLVM objects now take a 'Context' to make multi-threaded apps easier. Since we're not multi-threaded it's safe to use llvm::getGlobalContext() which gives us the same behavior as we had before.

module bug43;

struct S
{
    ubyte[3] vals;
}

void func(ubyte[3] v)
{
}

void main()
{
    S s;
    func(s.vals);
}
