[LinkerWrapper] Change wrapping to include jumps for other variables

[LinkerWrapper] Change wrapping to include jumps for other variables

Summary:
We don't currently support other variable types, like managed or
surface. This patch simply adds code that checks the flags and does
nothing. This prevents us from registering a surface as a variable as we
do now. In the future, registering these will require adding the flags
to the entry struct.
