"add inits to toplevel" and "call pattern heuristics" are only used in
code completion. Move them from LangOptions to CodeCompletionContext so
that they don't affect compiler arguments.
To describe fine grained priorities.
Introduce 'CodeCompletionFlair' that is a set of more descriptive flags for
prioritizing completion items. This aims to replace '
SemanticContextKind::ExpressionSpecific' which was a "catch all"
prioritization flag.
For example, non-Darwin platforms probably don't want
`#colorLiteral(red:green:blue":alpha:)` and `#imageLiteral(named:)`.
Add an completion option to include them, which is "on" by default.

struct Foo {
init(_ arg1: String, arg2: Int) {}
init(label: Int) {}
}
func test(strVal: String) {
_ = Foo(<HERE>)
}
In this case, 'strVal' was prioritized because it can use as an argument
for 'init(_:arg2:)'. However, argument labels are almost always
preferable, and if the user actually want 'strVal', they can input a few
characters to get it at the top. So we should always prioritize call
argument patterns.

Consolidate ThrowsKeyword, RethrowsKeyword, and AsyncKeyword to
EffectsSpecifierKeyword.
Abolish 'key.throwsoffset' and 'key.throwslength' as they aren't used.
Rather than replacing the code completion file
on the `CompilerInstance` whenever we do a cached
top-level completion, let's set a new main module
instead.
This allows us to properly update the
`LoadedModules` map, and allows the retrieval of
the code completion file to be turned into a
request.
When completing a single argument for a trailing closure, pre-expand the
closure expression syntax instead of using a placeholder. It's not valid
to pass a non-closure anyway.

Move the global PersistentParserState from
the CompilerInstance to the source file that code
completion is operating on, only hooking up the
state when it's needed. This will help make it
easier to requestify source file parsing.
Now
* NotApplicable: The result is not relevant for type relation (e.g.
keywords, and overloads)
* Unknown: the relation was not calculated (e.g. cached results), or the
context type is unknown.
* Invalid: The result type is invalid for this context (i.e. 'Void' for
non-'Void' context)
* Unrelated: The result type has no relation to the context type
* Convertible: The result type is convertible to the context type
* Identical: The result type is identical to the context type
To controls the lifetime of CompilerInstance within CompletionIntance.
- Prevent from using the same CompilerInstance from multiple completion
requests
- Separate the stacktrace between "fast" and "normal" completions
- Further code consolidation between various completion-like requests
- Introduce ide::CompletionInstance to manage CompilerInstance
- `CompletionInstance` vends the cached CompilerInstance when:
-- The compiler arguments (i.e. CompilerInvocation) has has not changed
-- The primary file is the same
-- The completion happens inside function bodies in both previous and
current completion
-- The interface hash of the primary file has not changed
- Otherwise, it vends a fresh CompilerInstance and cache it for the next
completion

codeCompleteOpen() has own sorting algorithm, codeComplete() calls this
sortCompletionResults() in its callback. So this pre-sorting is
completely unnecessary.
SwiftSourceInfo files provide source location information for decls coming from
loaded modules. For most IDE use cases it either has an undesirable impact on
performance with no benefit (code completion), results in stale locations being
used instead of more up-to-date indexer locations (cursor info), or has no
observable effect (live diagnostics, which are filtered to just those with a
location in the primary file).
For non-IDE clients of SourceKit though, cursor info providing declaration
locations for symbols from other modules is useful, so add a global
configuration option (and a new request to set it) to control whether
.swiftsourceinfo files are loaded or not based on use case (they are loaded by
default).
Get source locations from '.swiftsourceinfo' is currently expensive.
Since they are not necessary for code completion, set
'IgnoreSwiftSourceInfo' to 'true'.

- Use `performParseAndResolveImportsOnly()` to invoke the frontend
- Do `bindExtensions()` in `ide::typeCheckContextUntil()`
- Typecheck preceding `TopLevelCodeDecl`s only if the compleiton is in
a `TopLevelCodeDecl`
- Other related tweaks

The clang importer has to deal with two virtual file systems, one coming
from clang, and one coming from swift. Currently, if both are set, we
emit a diagnostic that we'll pick the swift one.
This commit changes that, by merging the two virtual file systems. The
motivation for this change is the reproducer infrastructure in LLDB,
which adds a third virtual file system to the mix.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances in the swift repo.
