[edk2] [PATCH 3/4] MdePkg/Include: Add VA list support for VS2017/ARM64

2018-02-23 Thread Pete Batard 
We need to explicitly call the built-in __va_start() for ARM64, otherwise
the variable parameters are not properly enqueued for the next function
calls.
Also do the same for ARM, as as it doesn't harm us.
