This is a limitation of the x86_32 backend. At the moment, shifts of 64-bit values are legalized to PSLLQ/PSRLQ (#1612) but there's no other applicable legalization rule at all. I wasn't sure what's a good way to legalize 64-bit shifts on 32-bit platforms so I went with the SIMD route that was similar to existing code. Suggestions for a better approach very much welcome!

the options being "rename SystemV to Ccc", "rename SystemV to Cdecl", "add Cdecl as an alias of SystemV for Windows alone", and "do nothing and just use SystemV on Windows x32"

"do nothing and just use SystemV on Windows x32" and "rename SystemV to Cdecl" sound like they might confuse people; at least, it would probably confuse me if I hadn't just read the rest of the post above :-).

I have a mild preference for "add Cdecl as an alias of SystemV for Windows alone", but I also wouldn't be opposed to "rename SystemV to Ccc" (and introduce a new variant for x86-64).

#1787 fixes that.

Triage: I believe that with the removal of x86_32 backend this PR is no longer relevant.
