63b78c86d9 Fix thumbv6m build (feature=c) 
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

b2aea631fe Collection of VFP intrinsics 
Nothing really exciting here. LLVM on hard-float target use native instructions
for all listed VFP intrinsics and so resulting implementation is really trivial.

Implemented intrinsics:

 __gesf2vfp
 __gedf2vfp
 __gtsf2vfp
 __gtdf2vfp
 __ltsf2vfp
 __ltdf2vfp
 __nesf2vfp
 __nedf2vfp
 __eqsf2vfp
 __eqdf2vfp
 __extendsfdf2vfp

0af69177f9 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.

97e6b3712a Add support for sub*f3vfp and add*f3vfp 
As done before for mul and div let's use extern "C" to generate `"aapcs"`
or `"aapcs-vfp"` depending on target configuration.

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!

cc3ea0ab93 Add test cases for Mul[s/d]f3vfp and Div[s/d]f3vfp

9a4e458b48 Add support for mul[s/d]f3vfp and div[s/d]f3vfp 
Here using `"C"` the compiler will use `"aapcs"` or `"aapcs-vfp"`
depending on target configuration.

Of course this translates in a call to `__aeabi_fdiv` / `__aeabi_fmul`
on non-HF targets.

On `eabi` targets with +vfpv2/vfpv3 LLVM generate:

   vmov	s0, r1
   vmov	s2, r0
   vdiv.f32	s0, s2, s0
   vmov	r0, s0
   bx	lr

On `eabihf` targets with +vfpv3-d16/d32/f32 +fp-only-sp LLVM generate:

  vdiv.f32	s0, s0, s1
  bx	lr

That's exactly what We need for [div/mul][s/d]f3vfp.S

b751493472 Fix some typos/bugs with float comparison intrinsics 
* I believe `__gtdf2` erroneously used `f32` instead of `f64`
* Most of these needed `#[arm_aeabi_alias]` to ensure they're correctly called
  through the alias
* Some existing aliases were corrected with the right names

2754f64c18 Skip aeabi_cdcmp and aeabi_cfcmp on big-endian targets 
First of all aeabi_cdcmp and aeabi_cfcmp are never called LLVM.
Second are little-endian only, so build fail on big-endian targets.
Temporally workaround: exclude these files for big-endian targets.

4fc3de624a Prepare this crate for more wasm32 compatibility 
This commit prepares the build script for a wasm32 target that doesn't use
Emcripten, notably forcing the `mem` feature to get activated and forcibly
ignoring the `c` feature, even if activated, for the wasm32 target.

e48cd1180b Use the Rust implementation of udivsi3 on ARM 
Although compiler-rt presumably has a more optimized implementation written in
assembly, it appears buggy for whatever reason, causing #173.

For now let's see if integration into rust-lang/rust will work with the
Rust-defined implementation!
