Resolve conflicts with changes since the 3.15 series:
* Convert `cmSystemTools::IsOn` => `cmIsOn`.
* Move one "EXCLUDE_FROM_ALL" target property logic fix to
its new location in `cmMakefile::AddNewUtilityTarget`.
The "all" target in each directory is supposed to have targets from that
directory even if the directory itself is marked `EXCLUDE_FROM_ALL` in
its parent. This was broken by commit dc6888573d (Pass EXCLUDE_FROM_ALL
from directory to targets, 2019-01-15, v3.14.0-rc1~83^2) which made the
participation of a target in "all" independent of context. Revert much
of the logic change from that commit to restore the old behavior. Then
re-implement the behavior intended by the commit to keep its test
working. Extend the test to cover the old behavior too.
Fixes: #19753
cmGeneratorExpression::Evaluate is a shortcut when only the evaluated string is
needed or an instance of cmCompiledGeneratorExpression cannot be cached.
Fixes: #19686
Set the MinTypeNameLength option to an impossibly high value in order
to limit the diagnostics to iterators. Leave new expressions and cast
expressions for later.
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
Provide a way for custom commands and targets to set the pool variable
of the ninja build statement. Setting `JOB_POOL` is not compatible with
`USES_TERMINAL`, which implies the `console` pool.
The option is silently ignored with other generators.
Closes: #18483
Suppress some cases in `Source/cmGeneratorExpressionNode.cxx` and
`Source/cmUVHandlePtr.h` where a few older compilers require a
user-defined default constructor (with `{}`).
When a target is created it now inherits the EXCLUDE_FROM_ALL property
from its directory. This change makes it possible to include a target
in "all", even if its directory has been marked as EXCLUDE_FROM_ALL.
The Ninja and Makefile generators were adding a space to the value both
before and after expanding rule variables. Only the latter is needed.
While at it, revise some outdated comments since the rule variable
expansion is no longer responsible for inserting the launcher.

Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

Ninja runs just one command line for every build statement, so the Ninja
generator needs to `&&`-chain multiple commands together into one long
string. For long custom command sequences this can exceed the maximum
command-line length for the operating system. In such cases, write the
commands out to a script instead, and then run the script from Ninja's
one command line.

Fixes: #15612
This enables configuration of build parallelism with the Ninja generator by
passing arguments on the command line to CMake. For example,
cmake \
'-DCMAKE_JOB_POOLS:STRING=compile=5;link=2' \
-DCMAKE_JOB_POOL_COMPILE:STRING=compile \
-DCMAKE_JOB_POOL_LINK:STRING=link \
~/src/MyProject
