Unrolled build for rust-lang#127047

Rollup merge of rust-lang#127047 - tspiteri:f128-aconsts-lsd, r=tgross35

fix least significant digits of f128 associated constants

While the numbers are parsed to the correct value, the decimal numbers in the source were rounded to zero instead of to the nearest, making the literals different from the values shown in the documentation.
