347dc132 - Reapply "[SimplifyCFG] Reuse function comdat for switch lookup table" (#193229)

Reapply "[SimplifyCFG] Reuse function comdat for switch lookup table" (#193229) This repplies https://github.com/llvm/llvm-project/pull/190995, after https://github.com/llvm/llvm-project/pull/192477 landed to fix the linker errors in the stage2 build caused by wrong merges of the comdat constants generated by this patch.
