Use clang-tidy's readability-simplify-boolean-expr checker.
After applying the fix-its, revise all changes *very* carefully.
Be aware of false positives and invalid changes.

Brad King 6052e4b3bf Merge topic 'improve-character-find-and-replace'
5784747d Improve string find: prefer character overloads.
5cec953e Use std::replace for replacing chars in strings.
2a1a2033 cmExtraEclipseCDT4Generator: use std::replace.
34bc6e1f cmCTestScriptHandler: don't call find repeatedly.

Brad King c13408279f Add a variable to specify language-wide system include directories
Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify
system include directories for for `<LANG>` compiler command lines.
This plays a role for include directories as the existing
`CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.

Kitware Robot d9fd2f5402 Revise C++ coding style using clang-format
Run the `Utilities/Scripts/clang-format.bash` script to update
all our C++ code to a new style defined by `.clang-format`.
Use `clang-format` version 3.8.

Brad King c7006d2ef1 cmGeneratorTarget: Protect macro code layout from clang-format
The `IMPLEMENT_VISIT_IMPL` macro must preserve a space before the `>`
character in case the `DATATYPE` is a template type ending in `>`.
Manually format the macro layout as clang-format would except for this
space.  Then add markup to tell clang-format not to format this macro.

Brad King 0ac18d40c8 Remove `//------...` horizontal separator comments
Modern editors provide plenty of ways to visually separate functions.
Drop the explicit comments that previously served this purpose.
Use the following command to automate the change:

    $ git ls-files -z -- \
        "*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" |
      egrep -z -v "^Source/cmCommandArgumentLexer\." |
      egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmDependsJavaLexer\." |
      egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmExprLexer\." |
      egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmFortranLexer\." |
      egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" |
      egrep -z -v "^Source/cmListFileLexer\." |
      egrep -z -v "^Source/cm_sha2" |
      egrep -z -v "^Source/(kwsys|CursesDialog/form)/" |
      egrep -z -v "^Utilities/(KW|cm).*/" |
      xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}'

This avoids modifying third-party sources and generated sources.

Brad King 64b5520346 Isolate formatted streaming blocks with clang-format off/on
The clang-format tool can do a good job formatting most code, but
well-organized streaming blocks are best left manually formatted.

Find blocks of the form

    os <<
      "...\n"
      "...\n"
      ;

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *("[^\n]*("|<<|;)$|;)\n){2,}'

Find blocks of the form

    os << "...\n"
       << "...\n"
       << "...\n";

using the command

    $ git ls-files -z -- Source |
      egrep -v -z '^Source/kwsys/' |
      xargs -0 pcregrep -M --color=always -B 1 -A 1 -n \
        '<<[^\n]*\n(^ *<<[^\n]*(\\n"|<<|;)$\n){2,}'

Surround such blocks with the pair

    /* clang-format off */
    ...
    /* clang-format on */

in order to protect them from update by clang-format.  Use the C-style
`/*...*/` comments instead of C++-style `//...` comments in order to
prevent them from ever being swallowed by re-formatting of surrounding
comments.

Brad King e1c7747253 Format include directive blocks and ordering with clang-format
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first).  First
run `clang-format` with the config file:

    ---
    SortIncludes: false
    ...

Commit the result temporarily.  Then run `clang-format` again with:

    ---
    SortIncludes: true
    IncludeCategories:
      - Regex:    'sys/types.h'
        Priority: -1
    ...

Commit the result temporarily.  Start a new branch and cherry-pick the
second commit.  Manually resolve conflicts to preserve indentation of
re-ordered includes.  This cleans up the include ordering without
changing any other style.

Use the following command to run `clang-format`:

    $ git ls-files -z -- \
        '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
      egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
      egrep -z -v '^Source/cm_sha2' |
      egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
      egrep -z -v '^Utilities/(KW|cm).*/' |
      egrep -z -v '^Tests/Module/GenerateExportHeader' |
      egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
      xargs -0 clang-format -i

This selects source files that do not come from a third-party.

Brad King 3144857e1e Avoid depending on CMAKE_ROOT cache entry internally (#16015)
Use cmSystemTools::GetCMakeRoot() which always knows the location of our
resources.  Do not depend on CMAKE_ROOT because the user could unset it
from the cache.

Milian Wolff 275f2a85b2 Remove temporary allocations when calling cmGeneratorTarget::GetName.
This happens quite often from within comparisons such as in
NamedGeneratorTargetFinder or FindGeneratorTargetImpl. It is the
top hotspot of both, number of allocations as well as number of
temporary allocations - the majority of calls lead to temporary
allocations.

In raw numbers, this patch removes ~1E6 temporary allocations of
1.5E6 temporary allocations in total when running the cmake daemon
on the KDevelop build dir. That is 2/3 of the total.

This hotspot was found with heaptrack.

Bartosz Kosiorek e76ee2c006 iOS: Fix framework resource directory layout (#15848)
A typical iOS application bundle (also Framework Bundle) contains the
application executable and any resources used by the application (for
instance, the application icon, other images, and localized content) in
the top-level bundle directory.  The same rule applies to Framework
Bundles.

Brad King 4ba760260b Android: Restore generation of non-versioned soname (#15851)
Our check of CMAKE_PLATFORM_NO_VERSIONED_SONAME, originally added by
commit v3.1.0-rc1~416^2 (Add basic Android platform module, 2014-06-06),
was dropped accidentally by commit v3.4.0-rc1~250^2~21
(cmGeneratorTarget: Move GetLibraryNames from cmTarget, 2015-08-04).
Restore the check in the new location of the GetLibraryNames method.
