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

aarch64: Exclude FP intrinsics on +nofp or +nosimd (#344) 
`AArch64` GCCs exit with an error condition when they encounter any kind of
floating point code if the `nofp` and/or `nosimd` compiler flags have been set.

Therefore, evaluate if those flags are present and set a boolean that causes any
compiler-rt intrinsics that contain floating point source to be excluded for
this target.

This patch prepares https://github.com/rust-lang/rust/pull/68334

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`

af3d2e0a3c Implement bcmp (#315) 
As of LLVM 9.0, certain calls to memcmp may be converted to bcmp, which I guess
could save a single subtraction on some architectures. [1]

bcmp is just like memcmp except instead of returning the difference between the
two differing bytes, it returns non-zero instead. As such, memcmp is a valid
implementation of bcmp.

If we care about size, bcmp should just call memcmp.
If we care about speed, we can change bcmp to look like this instead:
```rust
pub unsafe extern "C" fn bcmp(s1: *const u8, s2: *const u8, n: usize) -> i32 {
    let mut i = 0;
    while i < n {
        let a = *s1.offset(i as isize);
        let b = *s2.offset(i as isize);
        if a != b {
            return 1;
        }
        i += 1;
    }
    0
}
```

In this PR I do not address any changes which may or may not be needed for arm
aebi as I lack proper test hardware.
