7cdad114a5 math: compile math functions for Xous
This adds support for Xous, enabling users to call math functions on
primitives such as `cos()`.

Fix panic not being optimized out.
I don't know why it isn't being optimized out though, which worries
me.

This is still an experimental target but this should get the wasm64
target to behave more like wasm32.

Include Linux atomic emulation on androideabi
The old androideabi uses armv5 and thus also needs the atomic emulation
and because Android is basically Linux it can use the same
implementation.

Move from an "asm" flag to a "no-asm" feature flag (#386)
* Use a no-asm feature instead of an asm feature

This works better as core/alloc/std have trouble supporting default
featues in this crate.

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!

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`

41290fe728 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!

bd4a416457 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
