[Lldb-commits] Prevent type canonization when dereferencing

Hi Raphael,

I have a very similar test for a tool that integrates with lldb which
failed without the patch.
I thought the test in the patch would behave the same which is apparently
not the case.
Thanks for pointing that out. I will need to take another look and will get
back to you once I figure out what's wrong.
Sorry for the inconvenience.

kind regards,
