Check if MO would be a legal operand for a single-SGPR-read instruction.
Single-SGPR-read instructions typically accept VGPRs, SGPRs, or immediates as source operands. On gfx12+, if a source operand uses SGPRs, the HW can only read the first SGPR and replicate the value across all lanes. SrcN can be 0, 1, or 2, representing src0, src1, and src2, respectively. If MO is nullptr, the operand corresponding to SrcN will be used. Non-SGPR operands are always considered legal.

LDSDMA instructions act as both VALU and memory instructions, thus we also tag them as VALU.
However, in many places, we do not actually want to include LDSDMA instructions in this query. By setting AllowLDSDMA to false, this will return false for LDSDMA instructions.
