I have been meaning to do this change for a minute, but kept on putting it off.
This describes what is actually happening and is a better name for the option.
The layouts of resilient value types shipped in the Swift 5 standard library
x and overlays will forever be frozen in time for backward deployment to old
Objective-C runtimes. This PR ensures that even if the layouts of these types
evolve in the future, binaries built to run on the old runtime will continue
to lay out class instances in a manner compatible with Swift 5.
Fixes <rdar://problem/45646886>.
This patch allows `-serialize-diagnostics-path` for the interpret mode.
There is one file compiled in such mode, so it makes sense to support
this flag to specify an explicit output path for diagnostics emission.

In a previous commit, I banned in the verifier any SILValue from producing
ValueOwnershipKind::Any in preparation for this.
This change arises out of discussions in between John, Andy, and I around
ValueOwnershipKind::Trivial. The specific realization was that this ownership
kind was an unnecessary conflation of the a type system idea (triviality) with
an ownership idea (@any, an ownership kind that is compatible with any other
ownership kind at value merge points and can only create). This caused the
ownership model to have to contort to handle the non-payloaded or trivial cases
of non-trivial enums. This is unnecessary if we just eliminate the any case and
in the verifier separately verify that trivial => @any (notice that we do not
verify that @any => trivial).
NOTE: This is technically an NFC intended change since I am just replacing
Trivial with Any. That is why if you look at the tests you will see that I
actually did not need to update anything except removing some @trivial ownership
since @any ownership is represented without writing @any in the parsed sil.

Also add overloads for these operators to an extension of Array.
This allows us to typecheck array concatenation quickly with
designated type support enabled and the remaining type checker hacks
disabled.
Attempt to visit disjunctions that are associated with applies where
we have at least some useful information about the types of all of the
arguments before visiting other disjunctions.
Two tests here got faster, and one slightly slower. One of the
faster tests is actually moving from test/ to the slow/ directory in
validation-test because despite going from 16s to less than 1s, it was
still borderline for what we consider the slow threshold, so I made
the test more complex. The one that got a little slower is
rdar22022980, which I also made more complex so that it is clearly
"slow" by the way we are testing it.
slower:
rdar22022980.swift
faster:
rdar33688063.swift
expression_too_complex_4.swift
If the user specifies a memory threshold on the command-line, try to
honor that value and consider expressions too complex if we end up
allocating more memory than they specify.
Fixes rdar://problem/40952582 (aka https://bugs.swift.org/browse/SR-7525).
Explicitly mark the interpreter for the tool as windows does not
implicitly treat shebangs as the interpreter. This allows for the
proper invocation of the tool on Windows.
This converts the instances of the pattern for which we have a proper
substitution in lit. This will make it easier to replace it
appropriately with Windows equivalents.
The current implementation isn't really useful in the face of generic
overloads. It has never been enabled by default, and isn't useful to
keep around if it is disabled. If we ever want to bring it back,
we know where to look!
It's not you, it's us. We shouldn't tell the user their code is too complex, and "solve" doesn't mean anything to them in this context. Make it clearer this is an implementation limitation.
