cfallin opened PR #4247 from backport-4239-release-0.38 to release-0.38.0:

This is a cherry-pick of "x64 backend: fix to_amode with constant address (no registers). (#4239)"

If an address expression is given to to_amode that is completely
constant (no registers at all), then it will produce an Amode that has
the resulting constant as an offset, and (invalid_reg) as the base.
This is a side-effect of the way we build up the amode step-by-step --
we're waiting to see a register and plug it into the base field. If we
never get a reg though, we need to generate a constant zero into a
register and use that as the base. This PR adds a finalize_amode
helper to do just that.
