Tests if `x` is greater than or equal to `y`, elementwise.

Like `transmute`, but even less checked at compile-time: rather than giving an error for `size_of::<Src>() != size_of::<Dst>()`, it’s Undefined Behavior at runtime.

Returns whether we should perform some UB-checking at runtime. This eventually evaluates to `cfg!(ub_checks)`, but behaves different from `cfg!` when mixing crates built with different flags: if the crate has UB checks enabled or carries the `#[rustc_preserve_ub_checks]` attribute, evaluation is delayed until monomorphization (or until the call gets inlined into a crate that does not delay evaluation further); otherwise it can happen any time.

A SIMD vector with 64 elements of type `i64`.

A SIMD vector with one element of type `f32`.

Minimum possible normal power of 10 exponent. Use `f32::MIN_10_EXP` instead.
