If a semantic update finishes fast enough, the token snapshot may be
identical to the edit snapshot, but because of getBufferForSnapshot
consolidating edits into a new buffer, we were not detecting that case
properly, and it could cause an assertion failure (or potentially
incorrect range shifting in a release build). This would have reproduced
very rarely in practice, but I can reproduce it by putting `sleep(2)`
calls right before we read the semantic info in open and edit requests.
Incidentally, fix sourcekit-test and unit tests for the (rare) case
where an open or edit already has updated semantic info.
In order to avoid accidentally implicitly loading modules that are expected but were not provided as explicit inputs.
- Use either SerializedModuleLoader or ExplicitSwiftModuleLoader for loading of partial modules, depending on whether we are in Explicit Module Build or Implicit Module Build mode.
When performing an insertion (replacement length = 0) inside an existing
annotation, we were forming a closed range instead of a half-open range,
causing us to shift the effected token instead of throwing it out. There
were also no tests for this functionality, so add a bunch of annotations
tests.
One area thing that is not tested is what if there have been multiple
edits since the tokens were created. This is difficult to engineer,
because right now making an edit immediately removes the semantic tokens
and returns them. It could happen if the AST build takes longer than the
edits, but there is no way to guarantee that in the current API.

With an inverted pipeline, IRGen needs to be able
to compute the linker directives itself, so sink
it down such that it can be computed by the
`IRGenDescriptor`.
Return type in the closure signature is often redundant when expanding
placeholders, because the type of the clossures are usually inferred
from the context (i.e. calling function), users don't need to write the
return type explicitly.
They are not only redundant, but also sometimes harmful when the return
type is a generic parameter or its requirement. Actually, there is no
correct spelling in such cases.
So omit the return type and the parentheses around the parameter clause.

Previously we were linking in all SIL entities
if the input was a serialized non-SIB AST, and
`-disable-sil-linking` wasn't specified. However
none of the tests appear to want this behaviour.
Stop calling `SerializedSILLoader::getAll`, and
remove the `-disable-sil-linking` option, as this
is now the default behaviour.
Previously we would only link `.sib` partial
modules in SILGen, with other kinds of serialized
ASTs being linked just before the SILOptimizer if
`-sil-merge-partial-modules` was specified.
However linking them always seems to be the desired
behaviour, so adjust SILGen to link SIL for all
serialized AST inputs.
Do not remove semantic annotations, so that if a client sends multiple
magic replacetext 0, 0, "" requests they will all return the same
result. This makes sourcekitd more robust around providing semantic
highlighting if the editor may make multiple queries for document
update.

We weren't printing memberwise inits, shorthand arguments (e.g. $0, $1), and
other implicit decls, so cursor info would give empty annotated decl and fully
annotated decl fields for them.

This obviates the need for "-frontend", although we still accept it
for backward compatibility. Switch lit's %target-swift-frontend et al
over to calling swift-frontend.
Build swift-frontend as the primary Swift binary, and have
swift/swiftc/etc. symlink over to it. This is a step toward allowing
swift-driver to replace the swift and swiftc binaries.
This makes it easier to specify OptionSet arguments.
Also modify appropriate uses of ModuleDecl::ImportFilter to take
advantage of the new constructor.
