Some versions of HP-UX do not define 'isfinite' or 'finite' in math.h
for Itanium when preprocessing with C++, so we have to add the
definition ourselves instead to map to the internal version.
In commit a390de65 (Ninja: Generate separate compile and link rules for
each target, 2015-05-18) we removed the _RSP_FILE suffix from rule names
meant for targets that need to build with a .rsp file because we now use
per-target rules anyway. Remove this suffix from references to the rule
too.

The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first
merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property',
2013-06-05) but worked only for shared libraries and executables with
exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader:
Deprecate add_compiler_export_flags function., 2013-09-02) the
add_compiler_export_flags function was used to add visibility flags to
all targets.
The visibility flags are useful for sources in all target types because
they may be later linked into shared libraries or executables with
exports. Introduce policy CMP0063 to enable them for all target types
while preserving compatibility with existing projects that do not expect
this.
Don't create a snapshot in Initialize(), but leave the creation
responsibility to the cmake instance instead. Previously, the
cmState would Initialize() in its constructor, and the cmake instance
would re-Initialize() during Configure(). The end result was the
same and there would be one snapshot present. However, cmLocalGenerator
also created a snapshot on construction, and that one was used, leaving
the first snapshot unused, and potential for off-by-one errors.
Fix that by making the cmLocalGenerator use the existing snapshot
if it is top-level. Add a CurrentSnapshot to the cmake instance and
populated it while configuring a directory. This will eventually
replace the 'current local generator' concept. Fix the GetParent
implementation to be able to return the first snapshot.
The virtual methods are overrides not overloads, the constructor
is no longer a default variant, the destructor and GetCMakeInstance
comments add no value, only a typo.
Enable languages only in the individual test case. Enable the test
everywhere except Visual Studio generators (which do not implement the
properties) and just set fake flags as needed to activate relevant code
paths. Drop unneeded CMAKE_SUPPRESS_REGENERATION which seems to have
been copied from an unrelated test when this test was created.
Add an ExternalData_NO_SYMLINKS to enable use of copies instead of
symlinks to populate the real data files behind a DATA{} reference.
This will be useful on UNIX-like systems when the underlying filesystem
does not actually support symbolic links.

The 'ctest --launch' command must be placed before the IWYU launcher on
the compiler command line. Extend the RunCMake.IncludeWhatYouUse test
to cover this case. The Ninja generator already does it correctly.
