This change makes us treat it exactly as we do 'init'. We don't allow renaming the base name,
and don't fail if the basename doesn't match for calls.
Also:
- explicit init calls/references like `MyType.init(42)` are now reported with
'init' as a keywordBase range, rather than nothing.
- cursor info no longer reports rename as available on init/callAsFunction
calls without arguments, as there's nothing to rename in that case.
- Improved detection of when a referenced function is a call (rather than
reference) across syntactic rename, cursor-info, and indexing.

It looks like the only thing that fails is the linkage computation
for the dynamic replacement key of class methods. Even though
methods have hidden linkage to prevent them from being directly
referenced from outside a resilient module, we need to ensure
the dynamic replacement key is visible.
Fixes <rdar://problem/58457716>.
The client code doesn't actually call into these specialized functions even
though they have public linkage. This could lead to TBD verification failure
shown in rdar://44777994.
This patch also warns users' codebase when `export: true` is specified.
Support `@differentiable` function conversion for `init` references, in
addition to `func` references and literal closures. Minor usability improvement.

Make sure we mangle opaque types using the same settings as the
debugger mangling (with OptimizeProtocolNames = false) to ensure
that we can reconstruct those names again.
We already ban all structs from declaring storage that comes from implementation-only imports. Until now we missed property wrappers, they were just dropped in deserialization.

When merging many blocks to a single block (in the wrong order), instructions are getting moved over and over again.
This is quadratic and can result in very long compile times for large functions.
To fix this, always move the instruction to smaller block to the larger block.

To be precise: don't add instruction uses to the worklist if it already has more than 10000 elements.
This avoids quadratic behavior for very large functions.
rdar://problem/56268570
For functions which results in > 10000 nodes, just bail and don't compute the connection graph.
The node merging algorithm is quadratic and can result in significant compile times for very large functions.

Previously we could allow some invalid coercions to
sneak past Sema. In most cases these would either
cause crashes later down the pipeline or
miscompiles. However, for coercions between
collections, we emitted somewhat reasonable code
that performed a force cast.
This commit aims to preserve compatibility with
those collection coercions that previously
compiled, and emits a warning telling the user to
use either 'as?' or 'as!' instead.

wrapped value placeholder in an init(wrappedValue:) call that was previously

OpaqueValueExpr.
Extend SwiftDtoa to provide optimal formatting for Float16 and use that for `Float16.description` and `Float16.debugDescription`.
Notes on signaling NaNs: LLVM's Float16 support passes Float16s on x86
by legalizing to Float32. This works well for most purposes but incidentally
loses the signaling marker from any NaN (because it's a conversion as far
as the hardware is concerned), with a side effect that the print code never
actually sees a true sNaN. This is similar to what happens with Float and
Double on i386 backends. The earlier code here tried to detect sNaN in a
different way, but that approach isn't guaranteed to work so we decided to
make this code use the correct detection logic -- sNaN printing will just be
broken until we can get a better argument passing convention.

Make `SynthesizedFileUnit` attached to a `SourceFile`. This seemed like the
least ad-hoc approach to avoid doing unnecessary work for other `FileUnit`s.
TBDGen: when visiting a `SourceFile`, also visit its `SynthesizedFileUnit` if
it exists.
Serialization: do not treat `SynthesizedFileUnit` declarations as xrefs when
serializing the companion `SourceFile`.
Resolves TF-1239: AutoDiff test failures.
JVP functions are forward-mode derivative functions. They take original
arguments and return original results and a differential function. Differential
functions take derivatives wrt arguments and return derivatives wrt results.
`JVPEmitter` is a cloner that emits JVP and differential functions at the same
time. In JVP functions, function applications are replaced with JVP function
applications. In differential functions, function applications are replaced
with differential function applications.
In JVP functions, each basic block takes a differential struct containing callee
differentials. These structs are consumed by differential functions.
Make `ADContext` lazily create a `SynthesizedFileUnit` instead of creating one
during `ADContext` construction. This avoids always creating a
`SynthesizedFileUnit` in every module, since differentiation is a mandatory
transform that always runs.
It was nonetheless useful to test always creating a `SynthesizedFileUnit` for
testing purposes.
Add implicit declarations generated by the differentiation transform to a
`SynthesizedFileUnit` instead of an ad-hoc pre-existing `SourceFile`.
Resolves TF-1232: type reconstruction for AutoDiff-generated declarations.
Previously, type reconstruction failed because retroactively adding declarations
to a `SourceFile` did not update name lookup caches.
`SynthesizedFileUnit` is a container for synthesized declarations. Currently, it
only supports module-level declarations.
It is used by the SIL differentiation transform, which generates implicit struct
and enum declarations.
