Trevor Gross c7c5adbe64 compiler-builtins: Remove the no-f16-f128 feature 
This option was used to gate `f16` and `f128` when support across
backends and targets was inconsistent. We now have the rustc builtin cfg
`target_has_reliable{f16,f128}` which has taken over this usecase.
Remove no-f16-f128 since it is now unused and redundant.

compiler-builtins and libm

This repository contains two main crates:

  • compiler-builtins: symbols that the compiler expects to be available at link time
  • libm: a Rust implementation of C math libraries, used to provide implementations in core.

More details are at compiler-builtins/README.md and libm/README.md.
