[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 bug56;

void main()
{
    int[] a;
    a = [1,2,3];
    {int[] b = [4,5,6];}
}
