The `fluent_messages!` macro produces uses of `crate::{D,Subd}iagnosticMessage`, which means that every crate using the macro must have this import: ``` use rustc_errors::{DiagnosticMessage, SubdiagnosticMessage}; ``` This commit changes the macro to instead use `rustc_errors::{D,Subd}iagnosticMessage`, which avoids the need for the imports.

Currently we always do this: ``` use rustc_fluent_macro::fluent_messages; ... fluent_messages! { "./example.ftl" } ``` But there is no need, we can just do this everywhere: ``` rustc_fluent_macro::fluent_messages! { "./example.ftl" } ``` which is shorter.

Implements lane-local byte swapping through vector shuffles. While this is more setup than non-vector shuffles, this implementation can shuffle multiple integers concurrently. Signed-off-by: Andy Sadler <[email protected]>

The simd intrinsic handler was delegating implementation of `simd_frem` to `Builder::frem`, which wasn't able to handle vector-typed inputs. To fix this, teach this method how to handle vector inputs. Signed-off-by: Andy Sadler <[email protected]>

If we're running against a patched libgccjit, use an algorithm similar to what LLVM uses for this intrinsic. Otherwise, fallback to a per-element bitreverse. Signed-off-by: Andy Sadler <[email protected]>

gcc_not would panic upon encountering a vector type, which is not what we want here. Signed-off-by: Andy Sadler <[email protected]>

This test now passes when tested with a patched libgccjit. However, due to [some compiler bugs][1], we can't enable this for non-patched libgccjit yet.

`sess` is a terribly misleading name for a `Handler`! This confused me for a bit.
