Summary:
It is used by code completion and signature help. Code completion
already uses a special no-compile mode for missing preambles, so this change is
a no-op for that.
As for signature help, it already blocks for a preamble and missing it implies
clang has failed to parse the preamble and retrying it in signature help likely
will fail again. And even if it doesn't, request latency will be too high to be
useful as parsing preambles is expensive.

Summary:
It prevents code completion entirely in affected method bodies.
The main reason it's turned on is for compatibility with headers, so we turn it
off for the main file only. This is allowed because it's a compatible langopt.

This reverts commit 0788acbccb.
This reverts commit c2d7a1f79cedfc9fcb518596aa839da4de0adb69: Revert "[clangd] Add test for FindTarget+RecoveryExpr (which already works). NFC"
It causes a crash on invalid code:
class X {
decltype(unresolved()) foo;
};
constexpr int s = sizeof(X);
Summary:
The previous behavior was aggressive,
#include "abc/f^/abc.h"
foo/ -> candidate
"f/abc.h" is replaced with "foo/", this patch will preserve the "abc.h".

Summary:
Now Preferred is always the canonical (first) decl, Definition is always the def
if available.
In practice the index was already forcing this behaviour anyway, so there's no
change. (Unless you weren't using this index, in which case this patch makes
textDocument/declaration and toggling work as expected).

Summary:
clang-apply-replacements currently deduplicates all diagnostic replacements. However if you get a duplicated replacement from one TU then its expected that it should not be deduplicated. This goes some way to solving [[ https://bugs.llvm.org/show_bug.cgi?id=45150 | export-fixes to yaml adds extra newlines and breaks offsets. ]]
Take this example yaml.
```
---
MainSourceFile: '/home/nathan/test/test.cpp'
Diagnostics:
- DiagnosticName: readability-braces-around-statements
DiagnosticMessage:
Message: statement should be inside braces
FilePath: '/home/nathan/test/test.cpp'
FileOffset: 14
Replacements:
- FilePath: '/home/nathan/test/test.cpp'
Offset: 14
Length: 0
ReplacementText: ' {'
- FilePath: '/home/nathan/test/test.cpp'
Offset: 28
Length: 0
ReplacementText: '
}'
- DiagnosticName: readability-braces-around-statements
DiagnosticMessage:
Message: statement should be inside braces
FilePath: '/home/nathan/test/test.cpp'
FileOffset: 20
Replacements:
- FilePath: '/home/nathan/test/test.cpp'
Offset: 20
Length: 0
ReplacementText: ' {'
- FilePath: '/home/nathan/test/test.cpp'
Offset: 28
Length: 0
ReplacementText: '
}'
...```
The current behaviour is to deduplicate the text insertions at Offset 28 and only apply one of the replacements.
However as both of these replacements came from the same translation unit we can be confident they were both meant to be applied together
The new behaviour won't deduplicate the text insertion and instead insert both of the replacements.
If the duplicate replacement is found inside different translation units (from a header file change perhaps) then they will still be deduplicated as before.

`parseDocumentation` retains hard line breaks and removes soft line
breaks inside documentation comments.
Wether a line break is hard or soft is determined by the following rules
(some of which have been discussed in
https://github.com/clangd/clangd/issues/95):
Line breaks that are preceded by a punctuation are retained
Line breaks that are followed by "interesting characters" (e.g. Markdown
syntax, doxygen commands) are retained
All other line breaks are removed

Summary:
The ClangdVFSTest.TestStackOverflow unittest does not seem to work
when building the test with address sanitizer activated. Afaict the
goal is to get a constexpr depth error, rather than stack overflow.
But with asan instrumentation we do get stack overflow complaints
from asan. As a workaround this patch simply disables the test case,
when being built with address sanitizer activated.
