Defer visiting an instruction until its operands have been visited. Otherwise,
this pass will crash during ownership verification with invalid operand
ownership.

verifier crashes on @_addressableSelf)
(cherry picked from commit 16fffd1704)
Find all the usages of `--enable-experimental-feature` or
`--enable-upcoming-feature` in the tests and replace some of the
`REQUIRES: asserts` to use `REQUIRES: swift-feature-Foo` instead, which
should correctly apply to depending on the asserts/noasserts mode of the
toolchain for each feature.
Remove some comments that talked about enabling asserts since they don't
apply anymore (but I might had miss some).
All this was done with an automated script, so some formatting weirdness
might happen, but I hope I fixed most of those.
There might be some tests that were `REQUIRES: asserts` that might run
in `noasserts` toolchains now. This will normally be because their
feature went from experimental to upcoming/base and the tests were not
updated.
When a NoncopyableGenericsMismatch happens between the compiler and
stdlib, allow the compiler to rebuild the stdlib from its interface
instead of exiting with an error.
moveonly_addressors.swift (added in #70475) uses the experimental
feature `NonescapableTypes`, which requires an asserts compiler to work,
so requires marking the test as `REQUIRES: asserts`.
Mark the result of a move-only addressor as unresolved. The pointed-at value
cannot be consumed so ensure that only [read] or [modify] accesses are
performed. Update the move-only checker to recognize code patterns
from addressors.
