[clangd] Canonicalize compile flags before applying edits
Pushes input for the compile action to the end while separating with a
`--` before applying other manglings. This ensures edits that effect only the
arguments that come after them works, like changing parse language via -x.

Fixes https://github.com/clangd/clangd/issues/555.

Sam McCall 253b8145de [clangd] Avoid range-loop init-list lifetime subtleties.
The original code appears to be OK per the spec, but we've had 3 reports of
crashes with certain unofficial builds of clangd that look a lot like old
compilers (GCC 5.4?) getting lifetime rules wrong.

[clangd] Improve performance of dex by 45-60%
Take full advantage of AND's iterator children size estimation: use early reset
in sync() and prevent large overhead. The idea is that the children at the
beginning of the list are smaller and cheaper to advance. Very large children
negate the effect of this performance optimisation and hence should be
advanced only when absolutely necessary. By reducing the number of large
iterators' updates, we increase the performance by a large margin.

This change was tested on a comprehensive query dataset. The performance
boost increases with the average length of the query, on small queries it is
close to 45% but the longer they go the closer it gets to 60% and beyond.

Kirill Bobyrev 907efdf95d [clangd] Cleanup FuzzyFindRequest serialization and dex benchmark
* Due to the LLVM's JSON library changes (?), FuzzyFindRequest serialization is
  no longer valid since arrays are serialized as llvm::json::Array already.
  Hence, current implementation creates a nested array.
* YAML format is no longer the default, mention this for the benchmark.
* FIXME is no longer relevant. I ran benchmarks that showed no improvement with
  priority_queue years ago.

This seems to be a more useful behavior for tools that use preambles.
I believe it doesn't affect real compiles: the PCH is only included once
when used, and recursive inclusion of the main-file *within* the PCH

Sam McCall 4190017245 [clangd] Add tests covering existing header-guard behavior. NFC
A few different mechanisms here that will need some work to untangle:
 - self-include in a preamble being an error even if the file is ifdef-guarded
 - the is-include-guarded flag not being propagated from preamble to main ast
 - preambles containing the first half on an include guard discard that info

For now just record current behavior.

Sam McCall 462d4de35b [clangd] Add CMake option to (not) link in clang-tidy checks
This reduces the size of the dependency graph and makes incremental
development a little more pleasant (less rebuilding).

This introduces a bit of complexity/fragility as some tests verify
clang-tidy behavior. I attempted to isolate these and build/run as much
of the tests as possible in both configs to prevent rot.

Expectation is that (some) developers will use this locally, but
buildbots etc will keep testing clang-tidy.

Tim Northover 48c68a630e Recommit: Support: add llvm::thread class that supports specifying stack size.
This adds a new llvm::thread class with the same interface as std::thread
except there is an extra constructor that allows us to set the new thread's
stack size. On Darwin even the default size is boosted to 8MB to match the main
thread.

It also switches all users of the older C-style `llvm_execute_on_thread` API
family over to `llvm::thread` followed by either a `detach` or `join` call and
removes the old API.

Moved definition of DefaultStackSize into the .cpp file to hopefully
fix the build on some (GCC-6?) machines.

Sam McCall 26e1553a10 [clangd] CMake: express -Iclangd/ at top level and inherit
For files directly under clangd/, -Iclang-tools-extra/clangd (and the
equivalent for generated files) are not required, as CMake/the compiler puts
these directories on the include path by default.

However this means each subdirectory needs to
include_directories(.. ${CMAKE_CURRENT_BINARY_DIR}/..) etc, and this
proved annoying and error-prone to maintain and debug.

Since include_directories is inherited by subdirectories, we just
configure this explicitly at the top level instead.

This is a bit ugly, but it matches the former state and making Transport.h
