Simple Clamp Function
I thought this was more robust and easier to read. I also allowed this function to return early in order to skip the extra bound check (I'm sure the difference is negligible). I'm not sure if there was a reason for binding `self` to `x`; if so, please correct me.
Simple Clamp Function for f64

Add `IpDisplayBuffer` helper struct.
This removes the dependency on `std::io::Write` for implementing `Display`, allowing it to be moved to `core` as proposed in https://github.com/rust-lang/rfcs/pull/2832.
Support 128-bit atomics on all aarch64 targets
Some aarch64 targets currently set `max_atomic_width` to 64, but aarch64 always supports 128-bit atomics.

Fix nonsense non-tupled `Fn` trait error
Given this code:
```rust
#![feature(unboxed_closures)]
fn a<F: Fn<usize>>(f: F) {}
fn main() {
a(|_: usize| {});
}
```
We currently emit this error:
```
error[E0631]: type mismatch in closure arguments
--> src/main.rs:6:5
|
6 | a(|_: usize| {});
| ^ ---------- found signature of `fn(usize) -> _`
| |
| expected signature of `fn(usize) -> _`
|
note: required by a bound in `a`
--> src/main.rs:3:9
|
3 | fn a<F: Fn<usize>>(f: F) {}
| ^^^^^^^^^ required by this bound in `a`
For more information about this error, try `rustc --explain E0631`.
error: could not compile `playground` due to previous error
```
Notably, it says the same thing for "expected" and "found"!
Fix the output so that we instead emit:
```
error[E0308]: mismatched types
--> /home/gh-compiler-errors/test.rs:6:5
|
6 | a(|_: usize| {});
| ^ types differ
|
= note: expected trait `Fn<usize>`
found trait `Fn<(usize,)>`
note: required by a bound in `a`
--> /home/gh-compiler-errors/test.rs:3:9
|
3 | fn a<F: Fn<usize>>(f: F) {}
| ^^^^^^^^^ required by this bound in `a`
error: aborting due to previous error
```
The error could still use some work, namely the "mismatched types" part, but I'm leaving it a bit rough since the only way you'd ever get this error is when you're messing with `#![feature(unboxed_closures)]`.
Simply making sure we actually print out the difference in trait-refs is good enough for me. I could probably factor in some additional improvements if those are desired.

Rename Machine memory hooks to suggest when they run
Some of the other memory hooks start with `before_` or `after_` to indicate that they run before or after a certain operation. These don't, so I was a bit confused as to when they are supposed to run.
`memory_read` can be read two ways in English, "memory was read" or "this is a memory read" so without the prefix this was especially ambiguous.
