We need to do this since VMS has the following coding on status codes:
Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
The important thing to know is that odd numbers are considered
good, while even ones are considered errors.
Bits 3-15: actual status number
Bits 16-27: facility number. 0 is considered "unknown"
Bits 28-31: control bits. If bit 28 is set, the shell won't try to
output the message (which, for random codes, just looks ugly)
So, what we do here is to change 0 to 1 to get the default success status,
and everything else is shifted up to fit into the status number field, and
the status is tagged as an error, which is what is wanted here.
Finally, we add the VMS C facility code 0x35a000, because there are some
programs, such as Perl, that will reinterpret the code back to something
POSIX. 'man perlvms' explains it further.
NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
codes (status type = 1). I couldn't disagree more. Fortunately, the
status type doesn't seem to bother Perl.

/*
* Contemporary compilers implement lock-free atomic memory access
* primitives that facilitate writing "thread-opportunistic" or even real
* multi-threading low-overhead code. "Thread-opportunistic" is when
* exact result is not required, e.g. some statistics, or execution flow
* doesn't have to be unambiguous. Simplest example is lazy "constant"
* initialization when one can synchronize on variable itself, e.g.
*
* if (var == NOT_YET_INITIALIZED)
* var = function_returning_same_value();
*
* This does work provided that loads and stores are single-instruction
* operations (and integer ones are on *all* supported platforms), but
* it upsets Thread Sanitizer. Suggested solution is
*
* if (tsan_load(&var) == NOT_YET_INITIALIZED)
* tsan_store(&var, function_returning_same_value());
*
* Production machine code would be the same, so one can wonder why
* bother. Having Thread Sanitizer accept "thread-opportunistic" code
* allows to move on trouble-shooting real bugs.
*
* Resolving Thread Sanitizer nits was the initial purpose for this module,
* but it was later extended with more nuanced primitives that are useful
* even in "non-opportunistic" scenarios. Most notably verifying if a shared
* structure is fully initialized and bypassing the initialization lock.
* It's suggested to view macros defined in this module as "annotations" for
* thread-safe lock-free code, "Thread-Safe ANnotations"...
*
* It's assumed that ATOMIC_{LONG|INT}_LOCK_FREE are assigned same value as
* ATOMIC_POINTER_LOCK_FREE. And check for >= 2 ensures that corresponding
* code is inlined. It should be noted that statistics counters become
* accurate in such case.
*
* Special note about TSAN_QUALIFIER. It might be undesired to use it in
* a shared header. Because whether operation on specific variable or member
* is atomic or not might be irrelevant in other modules. In such case one
* can use TSAN_QUALIFIER in cast specifically when it has to count.

* There is subtle dependency on /volatile:<iso|ms> command-line option.
* "ms" implies same semantic as memory_order_acquire for loads and
* memory_order_release for stores, while "iso" - memory_order_relaxed for
* either. Real complication is that defaults are different on x86 and ARM.
* There is explanation for that, "ms" is backward compatible with earlier
* compiler versions, while multi-processor ARM can be viewed as brand new
* platform to MSC and its users, and with non-relaxed semantic taking toll
* with additional instructions and penalties, it kind of makes sense to
* default to "iso"...
