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

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.

dd0be67665 Remove mulsf3.c and muldf3.c from compiler-rt. 
mulsf3 and muldf3 have Rust implementations since 8970485. Remove the
C implementations to avoid conflicts.

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.

This is not used by LLVM/Rust, but is apparently used by gcc/C which jemalloc

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!

by one bit. This is legal when both values are equally close to the i128/u128.
