  • SR-9125 Value Witness Table handling for Windows

Issue Description:

Due to the semantics for PE/COFF, we need to indirect for module external symbol references. This makes emission of constant (or post relocation constant) data for the external pointers not possible. We need to instead locally define the VWT for module external types locally like vtables on Windows under the Microsoft ABI.
