The compiler (visual studio) may optimize some explicit strcmp call
in openssl source to use the intrinsic memcmp call.
In CrtLibSupport.h, we just use #define to mapping memcmp to
CompareMem API. So in Link phase, this kind of intrinsic optimization
will cause the "unresolved external symbol" error. For example:
OpensslLib.lib(v3_utl.obj) : error LNK2001:
unresolved external symbol _memcmp
This patch will keep the memcmp mapping, and provide extra Intrinsic
memcmp wrapper to satisfy the symbol link.

In a couple of places, OpenSSL code uses the address of the
strcmp() function, and assigns it to another comparator function
pointer.
Unfortunately, this falls foul of the inconsistent function ABI
that we use in EDKII. We '#define strcmp AsciiStrCmp' but AsciiStrCmp
is an EFIAPI function with the Microsoft ABI. And we're assigning its
address to a non-EFIAPI function, which may well have a different ABI.
Fix this by providing an actual strcmp() function in the default ABI.
We already *had* a prototype for it in OpenSslSupport.h, which was
then superseded by the #define strcmp AsciiStrCmp.
Now, OpenSSL code *can* use &strcmp without problems.
