I got as far as getting it to compile (patch attached) without breaking
5.10.1, but the tests segfault on 5.12.

SVt_RV can be #define'd to SVt_IV on >= 5.11.0. See
/usr/lib/perl/5.12/CORE/sv.h, which would take care of compatibility if
Alias.xs didn't #define PERL_CORE. (I understand this is very much frowned
upon for CPAN modules.)

OP_SETSTATE was disabled before 5.6.0 AFAICS and finally removed
in the 5.11 series.

The set of reverse dependencies is rather big, so this is going to be
something of a blocker.
