Auto merge of #128371 - andjo403:rangeAttribute, r=nikic

Add range attribute to scalar function results and arguments

as LLVM 19 adds the range attribute this starts to use it for better optimization.
hade been interesting to see a perf run with the rust-lang/rust#127513

closes rust-lang/rust#50156
cc rust-lang/rust#49572 shall be fixed but not possible to see as there is asserts that already trigger the optimization.
