number of vector registers rather than toggling between vector and scalar register number based on VF. I don't have a test case as I spotted this by inspection and on X86 it only makes a difference if your target is lacking SSE and thus has *no* vector registers. If someone wants to add a test case for this for ARM or somewhere else where this is more significant, that would be awesome. Also made the variable name a bit more sensible while I'm here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200211 91177308-0d34-0410-b5e6-96231b3b80d8
