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.
