Conversion from a wider to a narrower IEEE-754 floating-point type
...
Adds generic conversion from a wider to a narrower IEEE-754
floating-point type.
Implement `__truncdfsf2` and `__truncdfsf2vfp` and associated test-cases.

Fix some `use_c_shim_if` directives

This was an accidental regression introduced in #252 by removing compilation of
C files without adjusting the `#[use_c_shim_if]` directives. This restores the
compilation of the assembly files and updates the `#[use_c_shim_if]` directives.

Fix symbol collision caused by floatdisf
...
[PR #234 ](https://github.com/rust-lang-nursery/compiler-builtins/pull/234 ) added floatdisf implementation in rust and removed floatdisf.c from build.rs. However the removal is in-complete. In x86_64+!msvc environment, the symbol floatdisf would be generated twice. Bugs found in Redox OS issue [#1195 ](https://gitlab.redox-os.org/redox-os/redox/issues/1195 ) and Mesalink travis [log](https://travis-ci.org/mesalock-linux/mesalink/jobs/412928048 ) at line 738. This patch fixes it by removing floatdisf.c from this environment.

Apparently it doesn't compile due to an odd compiler error! This intrinsic has
to do with complex arithmetic anyway and we shouldn't need it.

Nothing really exciting here. LLVM on hard-float target use native instructions

__gtdf2vfp
__ltsf2vfp

__nesf2vfp

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!

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

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.
