Fix X64 native function call prolog. Prepare space for at least 4 arguments,
even if the native function's arguments are less than 4. From MSDN x64 Software Conventions, Overview of x64 Calling Conventions: “The caller is responsible for allocating space for parameters to the callee, and must always allocate sufficient space for the 4 register parameters, even if the callee doesn’t have that many parameters. This aids in the simplicity of supporting C unprototyped functions, and vararg C/C++ functions.” Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Samer El-Haj-Mahmoud elhaj@hp.com Reviewed by: Jiewen Yao <Jiewen.Yao@intel.com> Reviewed by: Feng Tian <Feng.Tian@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@16152 6f19259b-4bc3-4df7-8a09-765794883524
