[Bug target/38737] New: [4.4 Regression] __alignof__ (_Unwind_Exception) depends on -mavx
When -mavx was added BIGGEST_ALIGNMENT was changed to depend on it. This
changes the behavior of __attribute__((aligned)), which is used to define
struct _Unwind_Exception, and which changes the ABI of anything that uses it.
