MdePkg: Fix GCC Thunk support for IA32
In r11047 Ia32/Thunk.S was modified. However, the current implemention of Ia32/Thunk.S has contant values in the code which must be updated if the code is changed. This change updates those constants for the r11047 change. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11121 6f19259b-4bc3-4df7-8a09-765794883524
