Original API InitializeCpuExceptionHandlers is used in DxeMain to initialize exception handlers but it does not support setting up stack switch required by Stack Guard feature. Using the new API instead to make sure Stack Guard feature is applicable to most part of code. Since this API is called before memory service initialization, there's no way to call AllocateXxx API to reserve memory. Global variables are used for this special case. GDT table is reserved at least 2KB which should be big enough for all current use cases.
