* Avoid manual memory management
Prefer std::vector over malloc and free. This will allow removing goto
statements by leveraging RAII.
Use appropriate type (bool) to store overflow predicates and allocate
std::vector<bool> of appropriate sizes: before this change the
allocation was unnecessary bigger than required.
No longer attempt to catch "out of host memory" issues, given that in
such situation it is generally not possible to cleanly report an error.
Rely on std::bad_alloc exception to report such issues.
Introduce a new header for common code in the math_brute_force
component. It is currently complementary to utility.h and is expected to
hold cleaned up content extracted from future refactoring operations.
List all headers as source in CMake for better compatibility with IDEs.

* Remove manual or unnecessary memset
In order to use non-POD types as fields of TestInfo, memset must be

* Cleanup usage of static, extern and typedef
Remove static on functions defined headers, as it can result in
duplication in binaries.
Remove unnecessary extern keyword on a function declaration, as it is
the default behavior and can be puzzling when reading the code.
Remove the unused declaration of my_ilogb, which is never defined.
Remove unnecessary usage of typedef, as they are only increasing the
cognitive load of the code for no purpose.

* Improve usage of inline and static in harness
Functions declared in header as static can trigger unused warnings when
(indirectly) included in translation units that do not use such
functions. Use inline instead, which also avoids duplicating symbols in
binaries.

gWimpyBufferSize is never modified and is actually not used to modify
the number of tests -- gWimpyReductionFactor is used for that purpose by
some tests, but not all.
This patch removes this unnecessary global variable to simplify the

To reduce differences between tests, remove APPLE specific code from
unary tests as no other test have similar logic.
Ensure gMeasureTimes is consistently initialised regardless of operating
systems to ensure a consistent command line interface.
The remaining APPLE specific pieces of code relate either to include
paths, or to the implementation of PreventSleep(), ResumeSleep() and
GetTime(). Those are not removed in this commit.

* Fix enqueue_flags test to use correct barrier type.
Currently, enqueue_flags test uses CLK_LOCAL_MEM_FENCE.
Use CLK_GLOBAL_MEM_FENCE instead as all threads across work-groups
need to wait here.
* Add check for support for Read-Wrie images
Read-Write images have required OpenCL 2.x.
Read-Write image tests are already being skipped
for 1.x devices.
With OpenCL 3.0, read-write images being optional,
the tests should be run or skipped
depending on the implementation support.
Add a check to decide if Read-Write images are
supported or required to be supported depending
on OpenCL version and decide if the tests should
be run on skipped.
Fixes issue #894
* Fix formatting in case of Read-Write image checks.
Fix formatting in case of Read-write image checks.

Also, fix lengthy lines.
* Fix malloc-size calculation in test imagedim
unsigned char size is silently assumed to be 1
in imagedim test of test_basic.
Pass sizeof(type) in malloc size calculation.
Also, change loop variable from signed to unsigned.
Add checks for null pointer for malloced memory.
* Fix command-line function range for bruteforce
Runnning "test_bruteforce N M" is expected to skip
first N functions and test M functions after it.
When N is 0, the test currently skips M functions
and run all functions thereafter.
Fix the test to honor semantics of these
command-line options to correctly test
first M functions when N is 0.

* Permit half overflow within allowable ULP
Modify the algorithm for calculating half precision ULP error so
that it duplicates the behaviour of the single precision ULP algorithm,
in regards to allowing overflow within the defined ULP error.
In the case where the test value is infinity, but the reference is
finite, pretend the test value is 63336.0 and calculate the ULP error
against that.
Encountered this while testing half precision `hypot()` in PR !529,
for inputs `hypot(-48864.0, 43648.0)` which has reference
`65519.755799`. With RTE rounding this only just rounds to `65504` as half,
and returning INF is currently infinite ULP error. Using the leniency
introduced by this change however the error is `~0.5` within the `2` ULP
bounds defined by the spec.
* Run clang-format over changes
Code now conforms to style guidelines and allows `check-format.sh` to pass.
* OpenCL versions before 2.0 do not have precision requirements for
reduced precision math.
* Skip reduced precision testing for devices with
versions < 2.0.
* The global variable `gTestFastRelaxed` has state which is used to
control the behaviour of the compiler flag `-cl-fast-relaxed-math` and
the precision testing of relaxed, fp32 and fp64 types. This is confusing
since the global variable is being set and read in different translation
units, making it very difficult to reason about the logic of the brute
force framework. It is particular difficult to follow since the global
variables is cached and then turned off in the case of fp32 and f64 in
order to use the same code path as relaxed testing, after it is then
turned back on.
* Remove uses of the global variable outside of `main.cpp` (the global
variable remains in use within `main.cpp` since it is a command line
option and used to turn of relaxed testing completely). Replace all uses
of the global variable with boolean `relaxedMode` which is passed as a
function paramter but replaces `gTestFastRelaxed` semantically.
* Enable -Werror for GCC/Clang builds
Fixes many of the errors this produces, and disables a handful that
didn't have solutions that were obvious (to me).
* Check for `-W*` flags empirically
* Remove cl_APPLE_fp64_basic_ops support
* Undo NAN conversion fix
* Add comments to warning override flags
* Remove unneeded STRINGIFY definition
* Fix tautological compare issue in basic
* Use ABS_ERROR macro in image tests
* Use fabs for ABS_ERROR macro
* Move ABS_ERROR definition to common header
(Patch2)
A number of tests have got their own code for checking the presence of
extensions. This change replaces that code with is_extension_available
function.
