Maybe already deep into implementation but how are we going to deal with

(This kind of relocation also has to be done for stuff like
TypeInfo_Class). It needs initialization code to fill pvar with the
correct pointer.
Based on your saying that there are no absolute data relocations for
this on windows we'd have to perform runtime initialization.
At runtime it would simply copy _imp_var into pvar, right?
Do we support the same for pointers in TLS?
int* tlsvar = &var;
This might need initialization per thread, or patching the original TLS
segment.
No you can't take the address of a TLS var at compile time.
