On gfx11, with a sequence such as
s_trap 2
s_sendmsg sendmsg(MSG_DEALLOC_VGPRS)
s_endpgm
the s_sendmsg does deallocate registers while the wave is supposed to be
stopped. As a result, the wave cannot do the expected context save
operations, and cannot context save.
To avoid this problem, park the wave in the trap handler for gfx11.
Note that gfx11 has implemented an instruction cache prefetch. When
parked, the prefetch tries to access memory past the end of trap handler
which causes memory violation exceptions to be reported. To avoid this,
we need to add padding at the end of the trap handler. The padding
consists of `s_code_end` instructions Given that the trap handler is
loaded at a 0x1000 aligned address the maximum prefetch amount (in
bytes) is given by `256 - (trap_handler_size % 64)`.

This fixes a segfault error in cases where the linking order of
compilation unit varies. Reason behind the segfault is that one
global variable in one compilation unit depends on another global
variable in another compilation unit, but there is no guarantee that
this other compilation unit is initialized first. The fix forces a
reinitialization at the first invocation of the library.

status.priv may be read after returning from the trap handler, which

To work around this, added a s_waitcnt lgkmcnt(0) after s_sendmsg
to make sure the message is sent before continuing.

When compiling in ASAN mode, remap the first page of device allocations
to system memory. ASAN's memory allocator uses a small amount of extra
memory to store data for housekeeping purpose. But because this memory
is from the GPU memory pool, it might have uncommon memory type for host
to access. Mapping this section of memory to the host makes this memory
accessible to ASAN.

If the required scratch allocation is too large, ROCr will attempt to
reduce it by lowering the dispatch's targeted occupancy. The reduction
loop however was prone to overflow if waves_per_cu was not a multiple of
waves_per_group. Ensure no overflow by aligning waves_per_cu to
waves_per_group.
On GC 9.4.3 dGPU, dispatches with a large grid size and a
waves_per_group of e.g. 16 may require to reduce occupancy such that
waves_per_cu is less than waves_per_group to ensure the allocation size
is small enough. Allow this while also ensuring the tmpring scratch wave
count is kept divisible by the number of SEs per XCC.

gfx940 uses ttmp11 to hold the queue packet index so the first level
trap handler uses ttmp13 instead to save ib_sts.
Repurpose ttmp11[31] to mean that the ttmps are initialized. The issue
was that the debugger could not tell whether ttmp6 was written by the
trap handler when determining the stop reason.
If ttmp11[31]=0, then the trap handler has not been executed and ttmp6
should be assumed to be 0. If ttmp11[31]=1, then ttmp6 holds the
trap_id, if an s_trap instruction caused the exception.

On Linux, the os_thread abstraction is built on top of pthread. Many of
the pthread calls might fail and return error codes. The error
conditions are only checked via assertions (if ever checked) which means
that when doing a release build, no error condition is checked. The
same goes for dlsym/dlinfo and clock_gettime.
This commit improves the situation this by checking the error conditions
and acting accordingly. When the error condition is detected in a
function with a mean to indicate some error to its caller, then this
patch prints some error message and returns. If there is no way to
propagate the error up the call stack, print some error message and
abort the process.
For the os_info::os_info ctor, the only user is CreateThread, which
checks that the built thread is Valid(). If not, nullptr is returned to
the caller.
It could be possible to use exceptions when functions cannot pass
errors, but for now I only use abort as it is what abort would do with
debug build.
