implicit uses of the whole register when a sub register is defined. Now the same iterator is used in the rematerilization loop as in the spill loop later. Patch provided by Mikael Holmen. This fix was proposed and reviewed by Quentin Colombet, http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-August/076135.html. Unfortunately, this error in the rematerilization code has only been seen in a large test case for an out-of-tree target, and is probably hard to reproduce on an in-tree target. Therefore, no testcase is provided. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216873 91177308-0d34-0410-b5e6-96231b3b80d8
