sdma end ts must be 256 bit aligned in oss 3.0 and prior. Using
the ts pool requires copying into the signal and is a significant
performance penalty for small copies.
SharedSignal is 128 bytes due to alignment so can host the end ts.
Move sdma end ts into SharedSignal and remove ts pool and ts copy.

If M0[23] is set then the driver will interpret the interrupt as a
debug event, rather than a signal event.
Clear M0 before sending the interrupt. All paths here are terminal so
it's not necessary to save/restore M0.

Report traps and fatal exceptions through a wavefront's
amd_queue_t.queue_inactive_signal. Previously, only traps were
reported and requireed the compiler to pass in the signal pointer
in s[0:1].
The signal is obtained through a mapping from doorbell index to
amd_queue_t*. The doorbell is fetched within a wavefront through
the gfx9+ S_SENDMSG(MSG_GET_DOORBELL) instruction.

Assembler toolchains are moving from SP3 to LLVM. Replace trap handler
source code with LLVM equivalent.
Fix a trap issue with SQ_WAVE_IB_STS restore. Mostly harmless as all
traps are currently considered fatal to the wavefront.

[ROCm/ROCR-Runtime commit: 299874f17d]
Small times may be given to time conversion if GPU clocks are used to
accumulate elapsed time. Because HSA APIs deal in absolute time this
leads to large conversion offsets of order system uptime. Variation
in relative clock ratio estimation may be amplified in this case,
destroying elapsed time measurements.
This patch fixes the relative clock ratio used for times which predate
the call to hsa_init. This correlates errors in such times allowing
the elapsed time to be correctly computed.
The effective maximum system uptime before elapsed time conversion becomes
inaccurate is ~3.5 months. GPU event timestamps are good for process uptime
of ~3.5 months. These are limited by double's mantissa precision.

At the moment it is not possible to build ROCr with Clang. This is
a spurious limitation. The present PR addresses it by guarding GCC
only flags and by fixing some additional warnings that Clang triggers;
one of said warnings did outline a rather interesting issue with math
being done on void*s. - AlexVlx
Void ptr arithmetic had already been fixed in amd-master branch.

Prefer using memfd_create() for the ring buffer.
We were using /dev/shm, but this won't work on systems that
either don't have /dev/shm or have mounted it with noexec, because
for everything other than gfx700 we map the ring buffer with PROT_EXEC.
memfd_create() is Linux specific and was added in Linux 3.17, so we
will fallback to using /dev/shm on systems where memfd_create() is
not available.
