Avoid inlining floor into rem_pio2 
Possible workaround for
https://github.com/rust-lang/compiler-builtins/pull/976#issuecomment-3085530354

Inline assembly in the body of a function currently causes the compiler
to consider that function possibly unwinding, even if said asm
originated from inlining an `extern "C"` function. This patch wraps the
problematic callsite with `#[inline(never)]`.

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.

For instructions on contributing, see CONTRIBUTING.md.
