reflect: DeepEqual can return true for values that are not equal [1.14 backport] #39636
Description
@ianlancetaylor requested issue #39607 to be considered for backport to the next 1.14 minor release.
I think the bug was introduced by https://golang.org/cl/191940 for #33907. It's broken in 1.14 and tip but works in 1.13 and earlier.

@gopherbot Please open backport to 1.14.
