Currently the assertion in Alignment.h is triggered if a wrong value is passed -mstack-alignment option: ``` Assertion `(Value == 0 || llvm::isPowerOf2_64(Value)) && "Alignment is neither 0 nor a power of 2"' failed. ``` Added check in clang driver for the value of -mstack-alignment option, and emitted an error message when the wrong value was passed.
