rGc79bc5942d0e: [PowerPC][Bug] Fix Bug in Stack Frame Update Code
Summary

The stack frame update code does not take into consideration spilling
to registers for callee saved registers. The option -ppc-enable-pe-vector-spills
turns on spilling to registers for callee saved registers and may expose a bug
in the code that moves a stack frame pointer update instruction.
