Richard Smith da3dc0011e PR44684: Look through parens and similar constructs when determining
whether a call is to a builtin.

We already had a general mechanism to do this but for some reason
weren't using it. In passing, check for the other unary operators that
can intervene in a reasonably-direct function call (we already handled
'&' but missed '*' and '+').

This reverts commit aaae6b1b61,
reinstating af80b8ccc5, with a fix to
clang-tidy.

Haojian Wu ca9fd22adb [clangd] Set "spelled" flag for constructor references.
Summary:
DeclarationName for cxx constructor is special, it is not an identifier.
thus the "Spelled" flag are not set for all ctor references, this patch
fixes it.

Kirill Bobyrev 10540e480d [clangd] Filter out implicit references while renaming
This patch is based on D72746 and prevents non-spelled references from
being renamed which would cause incorrect behavior otherwise.

Kirill Bobyrev a6860c1af4
[clangd] Add a flag for spelled references in the Index
This patch allows the index does to provide a way to distinguish
implicit references (e.g. coming from macro expansions) from the spelled
ones. The corresponding flag was added to RefKind and symbols that are
referenced without spelling their name explicitly are now marked
implicit. This allows fixing incorrect behavior when renaming a symbol
that was referenced in macro expansions would try to rename macro
invocations.

Sam McCall 92570718a8 [clangd] Mechanism to make update debounce responsive to rebuild speed.
Summary:
Currently we delay AST rebuilds by 500ms after each edit, to wait for
further edits. This is a win if a rebuild takes 5s, and a loss if it
takes 50ms.

This patch sets debouncepolicy = clamp(min, ratio * rebuild_time, max).
However it sets min = max = 500ms so there's no policy change or actual
customizability - will do that in a separate patch.

Sam McCall b500c49cd4 [clangd] Don't mmap source files on all platforms --> don't crash on git checkout
Summary:
Previously we mmapped on unix and not on windows: on windows mmap takes
an exclusive lock on the file and prevents the user saving changes!

The failure mode on linux is a bit more subtle: if the file is changed on disk
but the SourceManager sticks around, then subsequent operations on the
SourceManager will fail as invariants are violated (e.g. null-termination).

This commonly manifests as crashes after switching git branches with many files
open in clangd.

Nominally mmap is for performance here, and we should be willing to give some
up to stop crashing. Measurements on my system (linux+desktop+SSD) at least
show no measurable regression on an a fairly IO-heavy workload: drop disk caches,
open SemaOverload.cpp, wait for first diagnostics.

Haojian Wu e864f93766 [clangd] Replace raw lexer code with token buffer in prepare rename.
Summary:
there is a slight behavior change in this patch:

- before: `in^t a;`, returns our internal error message (no symbol at given location)
- after: `in^t a, returns null, and client displays their message (e.g.
   e.g. "the element can't be renamed" in vscode).

both are sensible according LSP, and we'd save one `rename` call in the later case.
