[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 bug63;

void main()
{
    static void notnested()
    {
        printf("hello world\n");
    }
    notnested();
}
