Jorge Aparicio 3fa223505a make float* intrinsics testable on thumb
there are no intrinsics for float equality atm, so transmute to an integer
before comparing

fix infinite recursion in divmoddi4 / mulodi4

on ARMv7-M processors, divmoddi4 was calling mulodi4 and mulodi4 was calling
divmoddi4 leading to infinite recursion. This commit breaks the cycle by using
wrapping multiplication in divmoddi4.

fixes #145

use AAPCS calling convention on all aeabi intrinsics

also, on ARM, inline(always) the actual implementation of the intrinsics so we
end with code like this:

```
00000000 <__aeabi_dadd>:
    (implementation here)
```

instead of "trampolines" like this:

```
00000000 <__aeabi_dadd>:
    (shuffle registers)
    (call __adddf3)

00000000 <__adddf3>:
    (implementation here)
```

Jorge Aparicio 57085be2ea ARM: keep some non-aeabi symbols around
- multi3: there's no aeabi equivalent

- add{s,d}f3: required by the C sub{s,d}f3 implementation

but make sure they also use the AAPCS calling convention

i128 intrinsics

Adds i128 intrinsics.

Note that this PR doesn't do float intrinsics, due to the missing presence of macros, those are however still required in order for rustc to switch to this crate.

est31 37d349015e Disable quickcheck tests on mips
Two reasons:
    * the C versions __divti3 and __modti3 are apparently broken,
      at least when used in quickcheck. They change their own arguments.
    * compiler_rt's support for mips is disabled already on clang [1].
      Its desireable to support working "cargo test" on that compiler
      as well, and not greet the tester with linker errors.
