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.
Fix CI for thumb* targets
Main fix is inside `utest` (implement Termination to avoid ICE) all the rest are minor fixes due to the new `testcrate`.
Thumb6m needs some extra fixes: some undefined reference and a panic raised removing assembly implementation not in the list.
Still allow failures on TravisCI and keep my `utest` fork for a while. Let's see if is stable.
1. Avoid undefined references as:
undefined reference to `__modsi3'
undefined reference to `__umodsi3'
2. We can't remove assembly implementations that are not in the list
Collection of VFP intrinsics
Nothing really exciting here, just a list of trivial VFP intrinsics.
First of all set `mfloat-abi=hard` not only for thumb targets, then add support for the following intrinsics:
```
__gesf2vfp
__gedf2vfp
__gtsf2vfp
__gtdf2vfp
__ltsf2vfp
__ltdf2vfp
__nesf2vfp
__nedf2vfp
__eqsf2vfp
__eqdf2vfp
__extendsfdf2vfp
```
Resulting implementation is really trivial thanks to native code generated by LLVM on hard-float targets
Fix issue extending f32::MIN/MAX to f64 and improve testcrate.
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.
Be sure to do not mix hard-float and soft-float calls.
Disassembled code show exactly this.
So replace add with an explicit call to __addsf3/__adddf3
This seems the root cause of some sporadic failures.

Add generic conversion from a narrower to a wider FP type
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.
