Hmmm...

@sbc100 suggested the `-DiPTR trick`, which helped reduced the duplicate `WASM32-NEXT` vs `WASM64-NEXT` blocks.

I don't know if using `sed` in both spots really makes things any cleaner. Actually...that would probably be uglier.

Would have to do process substitution to replace `FileCheck %s` (which expects filename as a parameter) with something like `FileCheck <(sed 's/.../.../g' < %s`)`...

Unless I'm missing something?
