Update src/test/assembly/x86_64-floating-point-clamp.rs Simple Clamp Function I thought this was more robust and easier to read. I also allowed this function to return early in order to skip the extra bound check (I'm sure the difference is negligible). I'm not sure if there was a reason for binding `self` to `x`; if so, please correct me. Simple Clamp Function for f64 I thought this was more robust and easier to read. I also allowed this function to return early in order to skip the extra bound check (I'm sure the difference is negligible). I'm not sure if there was a reason for binding `self` to `x`; if so, please correct me.
