Dmitry Preobrazhensky d8ac03f15e [AMDGPU][GFX9][DOC][NFC] Update assembler syntax description
Summary of changes:
- Enable register tuples with 9, 10, 11 and 12 registers (https://reviews.llvm.org/D138205).
- Enable omod modifiers for v_max3_f16, v_min3_f16, etc. (https://reviews.llvm.org/D139469).
- Enable abs and neg modifiers for v_cndmask_b32 (https://reviews.llvm.org/D135900).
- Correct v_mov_b32_sdwa (it does not support abs and neg input modifiers yet).
- Enable tfe modifier for MUBUF loads (https://reviews.llvm.org/D137783).
- Enable image_gather4h (https://reviews.llvm.org/D130764).

.. _amdgpu_synid_gfx9_label:
label
=====
A branch target, which is a 16-bit signed integer treated as a PC-relative dword offset.
This operand may be specified as one of the following:
* An :ref:`integer_number<amdgpu_synid_integer_number>` or an :ref:`absolute_expression<amdgpu_synid_absolute_expression>`. The value must be in the range from -32768 to 65535.
* A :ref:`symbol<amdgpu_synid_symbol>` (for example, a label) representing a relocatable address in the same compilation unit where it is referred from. The value is handled as a 16-bit PC-relative dword offset to be resolved by a linker.
Examples:
.. parsed-literal::
offset = 30
label_1:
label_2 = . + 4
s_branch 32
s_branch offset + 2
s_branch label_1
s_branch label_2
s_branch label_3
s_branch label_4
label_3 = label_2 + 4
label_4:
