c774534b47 Use rdtsc instead of rdtscp. 
But rdtscp is serializing!

No, it's not. Quoting the Intel Instruction Set Reference:

"The RDTSCP instruction is not a serializing instruction, but it does
wait until all previous instructions have executed and all previous
loads are globally visible. But it does not wait for previous stores to
be globally visible, and subsequent instructions may begin execution
before the read operation is performed.",

"The RDTSC instruction is not a serializing instruction. It does not
necessarily wait until all previous instructions have been executed
before reading the counter. Similarly, subsequent instructions may begin
execution before the read operation is performed."

So, the difference is in waiting for prior instructions to finish
executing. Notice that even in the rdtscp case, execution of the
following instructions may commence before time measurement is finished
and data stores may be still pending.

But, you may say, Intel in its "How to Benchmark Code Execution Times"
document shows that using rdtscp is superior to rdstc. Well, not
exactly. What they do show is that when a *single function* is
considered, there are ways to measure its execution time with little to
no error.

This is not what Tracy is doing.

In our case there is no way to determine absolute "this is before" and
"this is after" points of a zone, as we probably already are inside
another zone.  Stopping the CPU execution, so that a deeply nested zone
may be measured with great precision, will skew the measurements of all
parent zones.

And this is not what we want to measure, anyway. We are not interested
in how a *single function* behaves, but how a *whole program* behaves.
The out-of-order CPU behavior may influence the measurements? Good! We
are interested in that. We want to see *how* the code is really
executed. How is *stopping* the CPU to make a timer read an appropriate
thing to do, when we want to see how a program is performing?

At least that's the theory.

And besides all that, the profiling overhead is now reduced.

37661fd2ee Fix 32 bit NEON version of DXT1 compression. 
This reverts commit b32e8fa24e.

Apparently it is possible to receive non-uniform data in alpha channel, which
breaks the original assumption about not needing the mask. This seemed to be a
problem only on 32 bit NEON implementation of DXT1 compression. Other
implementations handle such data without degradation of visual output.

7a6564feae Only recycle producers, if there's no data in queue. 
("The queue" is per-thread partial queue here.)

This fixes a problem where one thread writes to the queue, then is
terminated, making the (partially filled) queue available for other
threads to recycle. If another thread re-owns the queue, it will change
the associated thread id, while part of the queue was filled by the
original thread. This obviously created invalid data during dequeue.

The fix makes the recycling process check not only for queue inactivity
(which is marked when the original thread terminates), but also if the
queue is empty, preventing mixing data from different threads.

5fbb811f5d Degrade ARM timer to monotonic raw clock. 
The monotonic raw clock has the same accuracy as reading cntvct registers, but
using clock_gettime() has a measurable impact on queueing time (135 us vs
83 us).

This change is needed to enable ftrace time readings on ARM linux, which
doesn't provide any way to get raw cntvct readings, like x86-tsc on x86.

a56c47a6a0 Store thread handle in a thread local variable. 
This saves us a non-inlineable function call. Thread local block is
accessed anyway, since we need to get the token, so we already have the
pointer and don't need to get it a second time (which is done inside
Windows' GetCurrentThreadId()). We also don't need to store the thread
id in ScopedZone anymore, as it was a micro-optimization to save us the
second GetThreadHandle() call.

This change has a measurable effect of reducing enqueue time from ~10 to
~8 ns.

A further optimization would be to completely skip thread handle
retrieval during zone capture and do it instead on retrieval of data
from the queue. Since each thread has its own producer ("token"), the
thread handle should be accessible during the dequeue operation. This is
a much more invasive change, that would require a) modification of the
queue, b) additional processing of dequeued data to inject the thread
handle.

80dff1ede1 Add connection id for on-demand mode. 
Long-lived zones could send their end events without begin events in a
following scenario:

1. On-demand connection is made.
2. Zone begin is emitted, m_active is set to true.
3. Connection is terminated.
4. A new connection is made.
5. Zone end is emitted, because m_active is true.

To this point it was assumed that all zone end events will happen before
a new connection is made, but it's not necessarily true.

termination query. In both these cases there's no need to send data
anymore.

facb05f8cb Don't mark FastVector element as used until it's ready. 
This should prevent a race condition that would result in invalid last
element of the queue, in case a freezed thread already got the queue
item, but didn't wrote to it (or didn't wrote fully).

b371003336 In case of manual shutdown, don't wait for lock. 
All threads are freezed at this point, nothing will release it.

401ebd6f3d Use spin-lock in DequeueSerial. 
A thread freezed during crash processing may hold the lock and never
release it. The old behavior would cause deadlock in such situation. The
new one can be modified to work. Also, we don't want to use timed mutex.

0258f4a7b4 Handle crashes on windows. 
When a crash happens, put all threads (bar the profiler and crash
handling ones) into the freezer, send crash notification message,
request profiler shutdown and when it does, terminate process.

The list of ignored exceptions is sorta-kinda random at the moment and
may need further expansion.
