48c8b6a299 Current Thunk16.asm implementation clears reserved bits, which does not follow IA32 SDM. Now the fix is to only clear PAE and PSE bit of CR4 for real mode.

dccf78f0a2 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.
