Description
Is your feature request related to a problem? Please describe.
When analyzing x86 reps instruction's LLIL (which is lifted to a loop), there is no way to get the ILRegister and it’s version for a register (say rdi, rsi or rcx) at a given LLIL instruction.
Describe the solution you'd like
In MLIL SSA, I could use get_var_for_reg(register) and get_ssa_var_version(var) to get the SSAVariable. Similar APIs for LLIL SSA would solve the problem of accessing SSARegister
Describe alternatives you've considered
Mixing LLIL and MLIL for the analysis

Research direction
Start by reviewing the existing MLIL SSA APIs named in the issue, then locate the corresponding LLIL SSA and register representations in the public API. Done means an equivalent LLIL API can retrieve an SSARegister for a specified register at a given LLIL instruction without mixing LLIL and MLIL.
