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 <andrewsadler122@gmail.com>

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 <andrewsadler122@gmail.com>
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 <andrewsadler122@gmail.com>

gcc_not would panic upon encountering a vector type, which is not what we want here. Signed-off-by: Andy Sadler <andrewsadler122@gmail.com>
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.
