- Use the name for the cached module, so that we don't end up with a
zillion "x86_64-XXXXXXXX.swiftmodule" files in the cache when we're
working with architecture-specific swiftmodules.
- Diagnose if the expected name is different from the name specified
in the swiftinterface.
- Emit all diagnostics at the location of the import, instead of
without any location at all.
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.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Now that we don't store requirements in the GenericParamList, there's
no reason to use trailing records to list out the
GenericTypeParamDecls.
No functionality change.
A module compiled with `-enable-private-imports` allows other modules to
import private declarations if the importing source file uses an
``@_private(from: "SourceFile.swift") import statement.

Dynamic replacements are currently written in extensions as
extension ExtendedType {
@_dynamicReplacement(for: replacedFun())
func replacement() { }
}
The runtime implementation allows an implementation in the future where
dynamic replacements are gather in a scope and can be dynamically
enabled and disabled.
For example:
dynamic_extension_scope CollectionOfReplacements {
extension ExtentedType {
func replacedFun() {}
}
extension ExtentedType2 {
func replacedFun() {}
}
}
CollectionOfReplacements.enable()
CollectionOfReplacements.disable()
Otherwise, we can't represent a cross-reference to generic parameters
in a parent type /when used in an extension/.

The functionality change in this commit is that the control block in a
swiftdoc file is validated rather than just being ignored. Tests in
following commit.
This means that:
1. SILGenPattern always borrows the object before it emits a case.
2. Any cast with this cast has a +0 result.
NOTE: That one can not use this with address types (so we assert if you
pass this checked_cast_addr_br).
NOTE: Once we have opaque values, checked_cast_br of a guaranteed value will
lower to a copy + checked_cast_addr_br (assuming the operation is a consuming
cast). To make sure this does not become a problem in terms of performance, we
will need a pass that can transform SILGenPattern +0 cases to +1 cases. This is
something that we have talked about in the past and I think it is reasonable to
implement.
This is an incremental commit towards fixing SILGenPattern for ownership.

Add parsing, type checking, serialization, and deserialization support
for specifying multiple types as "designated" for operator lookup for
a given operator declaration.
The constraint solver still considers only the first type when
deciding the order to attempt the elements of a disjunction, so this
doesn't really change behavior yet.
Rather than limiting this to protocols, allow any nominal type.
Rename -enable-operator-designated-protocols to
-enable-operator-designated-types to reflect the change.
Augment the ASTPrinter to print the name and text of initializer expressions if
a property has an initializer and the type is @_fixed_layout and resides in a resilient module, and serialize the text for partial modules.
With this change, all .swiftinterface files in the project (except for SwiftLang) compile to swiftmodules on macOS.

Added the 'Module::getPrecedenceGroups' API to separate precedence group lookup
from 'Module::lookupVisibleDecls', which together with 'FileUnit::lookupVisibleDecls',
to which the former is forwarded, are expected to look up only 'ValueDecl'. In particular, this
prevents completions like Module.PrecedenceGroup.
Generic environments and archetypes can be expensive to deserialize
if they involve a generic signature not seen before.
Also, canonicalize the witness substitutions to eliminate type
aliases, and map them to interface types, which again are cheaper
to deserialize.
SILWitnessTable::Entry already contains a superset of what was supported
by SILDefaultWitnessTable::Entry, the latter of which only had “no entry”
and “method” states. Make SILDefaultWitnessTable::Entry an alias for
SILWitnessTable::Entry, and unify all of the parsing/printing/
(de)serialization logic.

...instead of std::vector, which (1) will always make separate
allocations, and (2) has features and overhead we don't need
I don't expect this to actually affect performance too much, but it
seems more correct for what Serialization needs anyway.
Not everything that goes into the "identifier table" is actually an
Identifier. If we don't need the string to be uniqued in the
ASTContext, don't bother calling getIdentifier.
May save some memory usage (and a string table lookup) for
deserialization.
serialization::BitOffset is set up for being in a PointerUnion, but in
this case that's not just overkill but actually wasteful, since we
have an extra flag to pack in. Use a raw bitfield instead.
No functionality change.
The recovery logic was erronously kicking in, because it was comparing
the substituted underlying type with the declaration's underlying type.
For a generic typealias, these never equal, so instead, serialize the
unsubstituted type, and substitute it in deserialization.
