Re #749. The first commit adds i686 to the test framework, so the CI should fail due to the issue being reported in #749. That's what I get locally as well, at least.

Hopefully this will help us catch any errors relating to 32-bit
environments. Cf. tectonic-typesetting#749.

The new i686 test is failing in the "right" place: in the otf_basic test after successfully building the code.

We were generating slightly different outputs on x86_64 vs. i686 due to
a floating-point rounding issue associated with the `unitsToPoints`
function. The function used single-precision, and things start agreeing
if we jump to double precision. So let's do that.

i686 is working now! Current CI failures are something that seems to have started spontaneously, unrelated to this PR.

It looks like we might need to update vcpkg to get those builds fully
working again, *and* this is a good excuse to update the PR in the hopes
that the new version of Rust (1.51) magically fixes the Windows test
failures that popped up.
