Previously, when the instruction had 3 operands, this would cause
possible corruption because of writing to sdwa->sel[2].
This was noticed thanks to GCC 10's -Wstringop-overflow warning.

It should reliably report the faulty shader but the faulty instruction
is inacurate, especially for memory violations because it's reported
when the addr is processed. It will be improved by emitting more
wait-states.

When TRAP_PRESENT is not enabled, all traps and exceptions are ignored.
Only EXCP_EN.mem_viol is currently supported because the other
exceptions have to be tested/validated first.
EXCP_EN.mem_viol is used to detect any sort of invalid memory
access like VM fault. When a memory violation is reported, the
hw jumps to the trap handler.

A trap handler is used to handle shader exceptions like memory
violations, divide by zero etc. The trap handler shader code will
help to identify the faulty shader/instruction and to report
more information for better debugging.
This has only been tested on GFX8, though it should work on GFX6-GFX7.
It seems we need a different implemenation for GFX9+.

It's way easier to write a trap handler shader using ACO IR
instead of writing disassembly by hand + clrxasm + copy&paste.
This trap handler is quite simple for now, it just loads a
buffer descriptor from the TMA BO, it saves ttmp0-1 which
contain various info about the faulty instruction, and it
stores some hw registers about the wave/trap status.

The TBA/TMA scalar registers are only available on GFX6-GFX8.
On GFX9+, TBA/TMA addr are stored in hardware registers and
the number of TTMP scalar registers is thus increased by 4.
Just keep in mind that tba_lo is actually ttmp0. Best would
be to support ttmp registers in RA but that's more complicated.
