Declare Function RtlAddFunctionTable Lib "kernel32.dll" (TODO) As TODO

This function only exists in this form on x64 and ARM. On Itanium, it exists with a different prototype. On x86, it doesn't exist at all! That's why the code analyzer is suppressed - it doesn't know what RtlAddFunctionTable is. I can attest to this prototype working on ARM, as in jailbroken Windows RT.
