[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.

void main()
{
    S t;
}

struct T
{
    int i;
    S* s;
}

struct S
{
    long i;
    T* t;
}
