2baa073fb1 Add emulated TLS support 
Currently LLVM uses emutls by default
for some targets (such as android, openbsd),
but rust does not use it, because `has_thread_local` is false.

This commit has some changes to allow users to enable emutls:

1. add `-Zhas-thread-local` flag to specify
    that std uses `#[thread_local]` instead of pthread key.
2. when using emutls, decorate symbol names
    to find thread local symbol correctly.
3. change `-Zforce-emulated-tls` to `-Ztls-model=emulated`
    to explicitly specify whether to generate emutls.

f9a228df48 Rename some arguments. 
`sess` is a terribly misleading name for a `Handler`! This confused me
for a bit.

remove generic-arithmetic-pass from failing tests 
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.

impl simd_bitreverse intrinsic 
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.

fix simd_frem intrinsic implementation 
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.

implement simd_bswap intrinsic 
Implements lane-local byte swapping through vector shuffles.  While this
is more setup than non-vector shuffles, this implementation can shuffle
multiple integers concurrently.

8e13be084a Use rustc_fluent_macro::fluent_messages! directly. 
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.

4de5d372aa Avoid need for {D,Subd}iagnosticMessage imports. 
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.
