When a semantic checking fails on a syntactic InitListExpr, we will
get an ill-formed semantic InitListExpr (e.g. some inits are nullptr),
using this semantic InitListExpr in clang (without setting the err-bits) is crashy.

In clang <3.9 the `unique_ptr` constructor that is supposed to allow
for Derived to Base conversion does not work. Remove this if we drop
support for such configurations.
This is the same fix as in fda901a987, and it updates the comments
to better reflect the actual issue. The same thing reproduces with
libc++ with older clangs.
Summary:
Clangd is returning current working directory for overriden commands.
This can cause inconsistencies between:
- header and the main files, as OverlayCDB only contains entries for the main
files it direct any queries for the headers to the base, creating a
discrepancy between the two.
- different clangd instances, as the results will be different depending on the
timing of execution of the query and override of the command. hence clangd
might see two different project infos for the same file between different
invocations.
- editors and the way user has invoked it, as current working directory of
clangd will depend on those, hence even when there's no underlying base CWD
might change depending on the editor, or the directory user has started the
editor in.
This patch gets rid of that discrepency by always directing queries to base or
returning llvm::None in absence of it.
For a sample bug see https://reviews.llvm.org/D83099#2154185.

Following on fcf7cc268f and 672207c319 which granted checks the ability to read boolean configuration arguments as `true` or `false`.
This enables storing the options back to the configuration file using `true` and `false`.
This is in line with how clang-format dumps boolean options in its style config.

Summary:
We only support Build/Skip for now, but with 'Load' or similar as an
option for future (load existing shards but don't build new ones).
This requires creating the config for each TU on startup. In LLVM, this
is 4000 occurrences for a total of 800ms on my machine.
But together with caching from D83755 it is only 25ms.

Differential Revision: https://reviews.llvm.org/D83768
Summary:
This is motivated by:
- code completion: nice to do no i/o on the request path
- background index: deciding whether to enqueue each file would stat the config
file thousands of times in quick succession.
Currently it's applied uniformly to all requests though.
This gives up on performing stat() outside the lock, all this achieves is
letting multiple threads stat concurrently (and thus finish without contention
for nonexistent files).
The ability to finish without IO (just mutex lock + integer check) should
outweigh this, and is less sensitive to platform IO characteristics.

Summary:
This is designed for tweaking compile commands by specifying flags to add/remove
in a config file. Something like:
CompileFlags: { Remove: -fcolor-diagnostics }
Having users tweak raw argv (e.g. with a regex) is going to end in tears: bugs
around clang-cl, xclang, aliases, joined-vs-separate args etc are inevitable.
This isn't in tooling because of the performance choices: build a big table
up-front to make subsequent actions fast. Maybe it should be though.

Summary:
This patch introduces basic textDocument/foldingRange support. It relies on
textDocument/documentSymbols to collect all symbols and uses takes ranges
to create folds.
The next steps for textDocument/foldingRange support would be:
* Implementing FoldingRangeClientCapabilities and respecting respect client
preferences
* Specifying folding range kind
* Migrating from DocumentSymbol implementation to custom RecursiveASTVisitor flow that will allow more flexibility
* Supporting more folding range types: comments, PP conditional regions, includes and other code regions (e.g. public/private/protected sections of classes, control flow statement bodies)
Tested: (Neo)Vim (coc-clangd) and VSCode.

Summary:
A few things were broken:
- use of Document::parseBlockNode() is incorrect and prevents moving to the
next doc in error cases. Use getRoot() instead.
- bailing out in the middle of iterating over a list/dict isn't allowed,
unless you are going to throw away the parser: the next skip() asserts.
Always consume all items.
- There were two concepts of fatal errors: error-diagnostics and drop-fragment.
(The latter is the "return false" case in the parser). They didn't coincide.
Now, parser errors and explicitly emitted error diagnostics are fatal.
