[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 fail2;

void a()
{
    b();
}

void b()
{
    c();
}

void c()
{
    d();
}

void d()
{
    int* ip;
    int i = *ip;
}

void main()
{
    a();
}
