This fixes nightly test 471.omnetep for Thumb1.

Log:
Transform @llvm.objectsize to integer if the argument is a result of malloc of known size.

It appears to be causing swb and nightly test failures.

someone could double-check.

This let's us build Wine on Darwin, and it gets the Qt build there a little bit
further (so Doug says).

most of them need. Update for the getInt8PtrTy() change.  Should be

The Windows build is just too weird; there's no real cost to doing the concurrency checks for ASTUnit in all builds

llvm-svn: 97840

   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.
