[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 scope4;
int main()
{
    int i;
    try
    {
        return i;
    }
    finally
    {
        //i = 1;
    }
}
