I'd suggest to start with what we already have in the tree.  Which is
(not fully sure the list is actually complete):

 - CryptoPkg/Library/Include/ carrying the bits needed to make openssl
   compile, and
 - CryptoPkg/Library/IntrinsicLib (again, for openssl, mostly IA32, some
   X64) and,
 - ArmPkg/Library/CompilerIntrinsicsLib (mostly ARM, some AARCH64).

Can we move that over to MdePkg so everyone can easily share it instead
of adding more copies of the same to the tree?

I have an old branch gathering dust doing that for the intrinsics, I can
try rebasing it to latest master next week ...

take care,
  Gerd
