[svn r261] Fixed debug info for integer and floating local variables, can now be inspected in GDB. Did a lot of smaller cleans up here and there. Replaced more llvm::Foo with LLFoo for common stuff. Split up tollvm.cpp.

module structs2;

struct S
{
    int i;
    char c;
    S* s;
    char[4] ca;
}

void main()
{
}
