Subject: 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
