PE RTS linker should learn how to relax 32-bit absolute relocations to PC-relative relocations
As noted in #18194, we can very easily end up in situations where the PE linker is unable to load code on Windows since we don't compile for PIC. Unfortunately, any long-lived GHCi session on Windows is almost destined to run into this.
While the long-term solution here is to introduce dynamic linking support on Windows, in the short term we can improve the situation by teaching the linker to relax 32-bit absolute relocations (e.g.
IMAGE_REL_AMD64_ADDR32) to a PC-relative relocation (e.g.
IMAGE_REL_AMD64_REL32). This won't be trivial as it will require that the linker learn to patch up instructions. Nevertheless, @Phyx and I suspect that it shouldn't be that hard to handle the common cases.
