no_diff diagnostics improvement (#7655)

2025-07-09T16:25:29+00:00

close #6286. This PR is to improve the diagnostics for no_diff usage. In a differentiable function, any calls to a non-diff function with constant arguments should not require no_diff attribute. This PR adds this extra check at `checkAutoDiffUsages` where it checks the differentiability on IR. In a differentiable method, we will force to use `[NoDiffThis]` attribute if there is access to non-differentiable `This` type. Once this access is detected we will report a warning to bring users attention that this access won't generate any derivative, they have to use `[NoDiffThis]` to suppress that warning. This PR adds this check at type checking stage, because it's the easiest way to find out all the `This` accesses.
