* 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.

* add 32 bit shift instructions to src/int/shift.rs
__ashlsi3
__ashrsi3

* add int_impl! for 16 bit numbers and large_int! for i32 and u32
* add tests in testcrate/build.rs
* 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`
Adds generic conversion from a wider to a narrower IEEE-754
floating-point type.
Implement `__truncdfsf2` and `__truncdfsf2vfp` and associated test-cases.
Now that `73884ae` is in some nightly release We can add ledf2vfp/leds2vfp
and so these two functions be aliased to aeabi_fcmple/aeabi_dcmple on soft-float targets.
I was able to trigger an issue extending f32::MAX or f32::MIN to a f64.
Issue was not triggered by `testcrate` mainly because f32::MAX/MIN are
not in the list of special values to generate.
This PR fix the issue and improve `testcrate` adding MAX/MIN/MIN_POSITIVE
in the list of special values.
Add `extend` module to implement conversion from a narrower to a wider
floating-point type.
This implementation is only intended to support *widening* operations.
Module to convert a *narrower* floating-point will be added in the future.
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!
