57deccf6de ARM: keep some non-aeabi symbols around 
- multi3: there's no aeabi equivalent
- divmod{s,d}i4: these are directly called by __aeabi_{l,i}divmod
- add{s,d}f3: required by the C sub{s,d}f3 implementation

but make sure they also use the AAPCS calling convention

Jorge Aparicio
3a4e6ce2f4 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)
```

e1fb75d02e Auto merge of #133 - est31:i128, r=japaric 
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.

70bda6dd1c 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.

rustc in debug mode with a plain multiplication will call @llvm.umul.with.overflow.* which may call the builtin resulting in infinite recursion.

3ed64e2b50 CI: use a recent nightly 
- add #[no_mangle] to the panic_fmt lang item to adjust to changes in
the visibility algorithm

- adjust to changes in the layout of Cargo's target directory

- use a newer Xargo to reduce the build time of the sysroot (only core
is compiled as part of the sysroot now)

42b4300d36 CI: use Xargo 0.2.x 
this version uses the rust-src component that rustup installs instead
of fetching the source tarball from static.r-l.o, which sometimes went
wrong due to the fallible logic that Xargo 0.1.x used
