Jakob Stoklund Olesen 53e000bac3 Better handling of dead super registers in LiveVariables. We used to do this: ...

CALL ... %RAX<imp-def>
   ... [not using %RAX]
   %EAX = ..., %RAX<imp-use, kill>
   RET %EAX<imp-use,kill>

Now we do this:

   CALL ... %RAX<imp-def, dead>
   ... [not using %RAX]
   %EAX = ...
   RET %EAX<imp-use,kill>

By not artificially keeping %RAX alive, we lower register pressure a bit.

The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously
55, anybody can see that. Sheesh.

DebugInfo

Remove test to check bugfix in handing debug info for global variables using intrinsics. Now, debug info for global variable is encoded using metadata. The old code path is now history and there is no need to have a test to check a bug fix in old code path.
