Latest `cc-rs` already manage all arm/thumb flags, so We can
safely remove this piece of code.

38d5777d98 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.

e3ac57b234 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.

33086672fa Don't build multc3 on AArch64 MSVC 
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.

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

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!

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

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.

e7c804a9b0 Expand and refactor teting infrastructure 
This commit moves over most of the testing infrastructure to in-tree docker
images that are all dispatched to from Travis (no other test configuration).
This allows versioning modifications to the test infrastructure as well as the
code itself. Additionally separate docker images allows for easy modification of
one without worrying about tampering of others as well as easy addition of new
targets by simply adding a new `Dockerfile`.

Additionally this commit bundles the master version of the `compiler-rt` source
repository from `llvm-mirror/compiler-rt` to test against. The compiler-rt
library itself is compiled as a `cdylib` which is then dynamically located at
runtime and we look for symbols in. There's a few hoops here, but they currently
get the job done.

All tests now execute against both gcc_s and compiler-rt, and this
testing strategy is now all hidden behind a macro as well (refactoring
all existing tests along the way).
