Summary:
Those errors are exposed at the first character of a file,
for a lack of a better place.
Previously, all errors were stored inside the AST and report
accordingly. However, errors in command-line argument parsing could
result in failure to produce the AST, so we need an alternative ways to
report those errors.
We take the following approach in this patch:
- buildCompilerInvocation() now requires an explicit DiagnosticConsumer.
- TUScheduler and TestTU now collect the diagnostics produced when
parsing command line arguments.
If pasing of the AST failed, diagnostics are reported via a new
ParsingCallbacks::onFailedAST method.
If parsing of the AST succeeded, any errors produced during
command-line parsing are stored alongside the AST inside the
ParsedAST instance and reported as previously by calling the
ParsingCallbacks::onMainAST method;
- The client code that uses ClangdServer's DiagnosticConsumer
does not need to change, it will receive new diagnostics in the
onDiagnosticsReady() callback
Errors produced when parsing command-line arguments are collected using
the same StoreDiags class that is used to collect all other errors. They
are recognized by their location being invalid. IIUC, the location is
invalid as there is no source manager at this point, it is created at a
later stage.
Although technically we might also get diagnostics that mention the
command-line arguments FileID with after the source manager was created
(and they have valid source locations), we choose to not handle those
and they are dropped as not coming from the main file. AFAICT, those
diagnostics should always be notes, therefore it's safe to drop them
without loosing too much information.

The bitstream reader handles errors poorly. This has two effects:
* Bugs in file handling (especially modules) manifest as an "unexpected end of
file" crash
* Users of clang as a library end up aborting because the code unconditionally
calls `report_fatal_error`
The bitstream reader should be more resilient and return Expected / Error as
soon as an error is encountered, not way late like it does now. This patch
starts doing so and adopting the error handling where I think it makes sense.
There's plenty more to do: this patch propagates errors to be minimally useful,
and follow-ups will propagate them further and improve diagnostics.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and

Standardize on the most common namespace setup in our *.cpp files:
using namespace llvm;
namespace clang {
namespace clangd {
void foo(StringRef) { ... }
And remove redundant llvm:: qualifiers. (Except for cases like
make_unique where this causes problems with std:: and ADL).
This choice is pretty arbitrary, but some broad consistency is nice.
This is going to conflict with everything. Sorry :-/
Squash the other configurations:
A)
using namespace llvm;
using namespace clang;
using namespace clangd;
void clangd::foo(StringRef);
This is in some of the older files. (It prevents accidentally defining a
new function instead of one in the header file, for what that's worth).
B)
namespace clang {
namespace clangd {
void foo(llvm::StringRef) { ... }
This is fine, but in practice the using directive often gets added over time.
C)
namespace clang {
namespace clangd {
using namespace llvm; // inside the namespace
This was pretty common, but is a bit misleading: name lookup preferrs
clang::clangd::foo > clang::foo > llvm:: foo (no matter where the using
directive is).

Summary:
For index-based code completion, send an asynchronous speculative index
request, based on the index request for the last code completion on the same
file and the filter text typed before the cursor, before sema code completion
is invoked. This can reduce the code completion latency (by roughly latency of
sema code completion) if the speculative request is the same as the one
generated for the ongoing code completion from sema. As a sequence of code
completions often have the same scopes and proximity paths etc, this should be
effective for a number of code completions.

Summary:
Sema code complete in the recovery mode is generally useless. For many
cases, sema first completes in recovery context and then recovers to more useful
context, in which it's favorable to ignore results from recovery (as results are
often bad e.g. all builtin symbols and top-level symbols). There is also case
where only sema would fail to recover e.g. completions in excluded #if block.
Sema would try to give results, but the results are often useless (see the updated
excluded #if block test).

Summary:
log() is split into four functions:
- elog()/log()/vlog() have different severity levels, allowing filtering
- dlog() is a lazy macro which uses LLVM_DEBUG - it logs to the logger, but
conditionally based on -debug-only flag and is omitted in release builds
All logging functions use formatv-style format strings now, e.g:
log("Could not resolve URI {0}: {1}", URI, Result.takeError());
Existing log sites have been split between elog/log/vlog by best guess.
This includes a workaround for passing Error to formatv that can be
simplified when D49170 or similar lands.

Summary:
The library has graduated from clangd to llvm/Support.
This is a mechanical change to move to the new API and remove the old one.
Main API changes:
- namespace clang::clangd::json --> llvm::json
- json::Expr --> json::Value
- Expr::asString() etc --> Value::getAsString() etc
- unsigned longs need a cast (due to r336541 adding lossless integer support)
