* Don't recalculate image parameters repeatedly in `test_read_image()`
We've already done this in the loop. There's no need to recalculate
those parameters over and over again in `sample_image_pixel*()` and
`read_image_pixel*()`. This should save some work during the image
streams test.
This only affects the 3D tests for now, but my time profiles indicate
this is where we spend the most time anyway.
* Vectorize read_image_pixel_float() and sample_image_pixel_float() for SSE/AVX
This shortens the image streams test time from 45 minutes without it to
37 minutes. Unfortunately, most of the time is now spent waiting for
memory, particularly in the 3D tests, because the 3D image doesn't
neatly fit in the cache, especially in the linear sampling case, where
pixels from two 2D slices must be sampled. Software prefetching won't
help; it only helps when execution time is dominated by operations, but
this is dominated by memory access. Randomized offsets are likely a
factor, because they throw off the hardware prefetcher.
One possible further optimization is, in the linear sampling case, to
load two sampled pixels at once. This is easy to do using AVX, which
extends SSE with 256-bit vectors.
Obviously, this only applies to x86 CPUs with SSE2. The greatest
performance gains, however, are seen with SSE4.1. Most modern x86 CPus
have SSE4. Work is needed to support other CPUs' vector units--ARM
Advanced SIMD/NEON is probably the most important one. Another
possibility is arranging the code so that the compiler's
autovectorization will kick in and do what I did here manually.
It only contains a pointer type definition for test functions that
really ought to be provided by testHarness.h.

While testing an OpenCL driver with ThreadSanitizer enabled the
OpenCL-CTS suffers from thread leaks in conversions and bruteforce on
posix systems. This is because `pthread_join` is never called in
`ThreadPool_Exit` for the `pthread_t`s created by the thread pool.
Instead, the threads are only informed to stop waiting on the condition
variable which unblocks the worker thread but does not clean up after
itself.
```

ThreadPool: thread 5 exiting.
ThreadPool: thread 4 exiting.

SUMMARY: ThreadSanitizer: thread leak (OpenCL-CTS/buildbin/conversions/test_conversions+0x35b2c) in ThreadPool_Init()
```
This patch adds global state to keep track of the `pthread_t`s created
by `pthread_create` in `ThreadPool_Init`. The list of `pthread_t`s is
then used by `ThreadPool_Exit` to call `pthread_join` to cleanup the
`pthread_t`s correctly.
A near identical example, and additional explanation, can be found on
[stackoverflow](https://stackoverflow.com/questions/72435574/thread-leak-detected-when-using-condition-variable-instead-of-join-with-pthrea).
On the Windows path, a similar change is not necessary because
`_beginthread` is used which automatically cleans up after itself when
the worker thread function returns.
The main sources of warnings were:
* Printing of a `size_t` which requires the `%zu` specifier.
* Printing of `cl_long`/`cl_ulong` which is now done using the
`PRI*64` macros to ensure portability across 32 and 64-bit builds.

Improve the design of the MTdataHolder wrapper:
* Make it a class instead of a struct with a private member, to make
it clearer that there is no direct access to the MTdata member.
* Make the 1-arg constructor `explicit` to avoid unintended
conversions.
* Forbid copy construction/assignment as MTdataHolder is never
initialised from an MTdataHolder object in the codebase.
* Define move construction/assignment as per the "rule of five".
Use the MTdataHolder class throughout math_brute_force, to simplify
code by avoiding manual resource management.

ThreadSanitizer detects some data race in ThreadPool. They stem from
inappropriate usage of volatile which are replaced with std::atomic
variables in this patch.
This patch focuses on data races identified while running the
math_brute_force component. For example, it doesn't fully remove usage
of ThreadPool_AtomicAdd from other components of the CTS. Furthermore,
thread leaks, most likely because threads are not joined, are not
addressed.

The CL_UNORM_SHORT_555 and CL_UNORM_INT_101010 formats contain padding
bits which need to be ignored in clCopyImage and clFillImage testing.
For clFillImage tests, padding was not ignored for the CL_UNORM_SHORT_555
format, and was ignored for CL_UNORM_INT_101010 by modifying actual and
reference data. For clCopyImage tests, padding was not ignored, both for
CL_UNORM_SHORT_555 and for CL_UNORM_INT_101010.
Fix this by adding a new compare_scanlines() function, which is used for
both of these formats, and does not modify the actual or reference data.
