Now that the X86 Maximal Stack Alignment Check pass has been removed (i.e.,
r168627), we no longer need to call the freezeReservedRegs() function a second time. Previously, this pass was conservatively adding the FP to the set of reserved registers, requiring the second update to the reserved registers. rdar://12719844 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168631 91177308-0d34-0410-b5e6-96231b3b80d8
