eaab1bf2 - [StackColoring] Remap FixedStackPseudoSourceValue frame index referenced by MachineMemOperand

[StackColoring] Remap FixedStackPseudoSourceValue frame index referenced by MachineMemOperand StackColoring::remapInstructions() remaps MachineOperand frame index (e.g. %stack.1 -> %stack.0) but does not remap FixedStackPseudoSourceValue frame index (e.g. store 4 into %stack.1.ap2.i.i) referenced by MachineMemoryOperand. This can cause an assertion failure when LiveDebugValues references a dead stack object. It is difficult to craft a test case. -g, va_copy and stack-coloring are required. I can only reproduce it on ppc32.
