We will also need to have  different llvm-ir for FP8 because its properties is different from the non-fp8.
Fp8 llvm-ir needs to have: IntrInaccessibleMemOnly, IntrHasSideEffects
And the SME_OuterProduct_TMOP_Intrinsic, should only have: IntrNoMem, IntrHasSideEffects
The attribute IntrInaccessibleMemOnly is only needed in the FP8 because of FPMR register
