The registers used to passed arguments to the DxeCore entrypoint in the inline assembly function InternalSwitchStackAsm() where switched at compilation time.

2011-08-02MdePkg: Fixed hang/reset in thunk code when building with GCC X64geekboy15a
Reverted changes of data areas from .long back to .space 4. This was done because the size of .long is based off of .int and may vary. Using a fixed size is required because these values are for patching code. Also note that .space will automatically initialize the data to zero. Not initializing all values to zero was causing the hang/reset.
