lint: Allow improper_ctypes_definitions (#364)
https://github.com/rust-lang/rust/pull/72700 caused the existing
`allow(improper_ctypes)` guard to stop working, we now need
`allow(improper_ctypes_definitions)` instead.

We keep the old one to avoid any issues with older nightlies.

Expand wasm32 testing on CI (#360)
* Expand wasm32 testing on CI

Run the full `run.sh` test script to get full assertions, including that
nothing in the wasm compiler-builtins is panicking. Unfortunately it's
currently panicking, so this is good to weed out!

* Update libm

Gate atomic intrinsics on presence of instructions (#324)
Don't emit the intrinsics for platforms which don't actually have the
instructions to do atomic loads/stores.

Closes #322

Allow FFI-unsafe warnings for u128/i128 (#323)
* Allow FFI-unsafe warnings for u128/i128

Handle new warnings on nightly, and we shouldn't need to worry about
these with compiler-builtins since this is tied to a particular compiler.

* Clean up crate attributes

* No need for stability marker
* Rustdoc docs not used for this crate
* Remove old build-system related cruft from rustc itself.

* Run `cargo fmt`

Cyryl Płotnicki b570ccfd2d Fix compilation on new nightly.
Compilation on rustc 1.33.0-nightly (c76f3c374 2019-01-18) failed with
```
error: the feature `cfg_target_vendor` has been stable since 1.33.0 and no longer requires an attribute to enable
  --> src/lib.rs:19:12

19 | #![feature(cfg_target_vendor)]
   |            ^^^^^^^^^^^^^^^^^

```

Removed the attribute to make it compile.

Alex Crichton 2a13475197 Simplify how testing is done
All tests are moved to a separate crate in this repository to enable features by
default. Additionally the test generation is moved to a seprate build script and
simplified to reduce the amount of boilerplate needed per test.

Overall this should still be testing everything, just in a different location!

Alex Crichton 2f2bb32e40 Use traits instead of macros for shift intrinsics
This is an attempt to tidy up the definition of intrinsics by making them more
rust-like at the definition site and using traits instead of macros for the
definition. Additionally the helper macro, `intrinsics!`, now fills in a
definition for #[cfg]'d off intrinsics when compiling with C code

Jorge Aparicio dfa7b161aa use AAPCS calling convention on all aeabi intrinsics
also, on ARM, inline(always) the actual implementation of the intrinsics so we
end with code like this:

```

    (implementation here)
```

instead of "trampolines" like this:

```
00000000 <__aeabi_dadd>:
    (shuffle registers)
    (call __adddf3)

00000000 <__adddf3>:
    (implementation here)
```
