bd4a416457 Use traits instead of macros for shift intrinsics 
This is an attempt to tidy up the definition of intrinsics by making them more
rust-like at the definition site and using traits instead of macros for the
definition. Additionally the helper macro, `intrinsics!`, now fills in a
definition for #[cfg]'d off intrinsics when compiling with C code

6eeab2e62f floattidf, floatuntidf: ignore differences smaller than 2 in test 
Its possible that the generated f64 is different from the expected one

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)
```

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.

I've openend nagisa/rust_libloading#19 to track that. Wel'll have to wait until that's fixed.

e4997a2026 hide the thumbv* target files 
due to how Cargo works, the rustc-cfg in build.rs was picking our target
specifications rather than the one the user meant to use. Placing our
target files in any place other than the root of the Cargo project
avoids the issue.

notable changes in the docker-based testing infrastructure

- the docker containers can now modify $CARGO_HOME, to re-use the outer
  Cargo registry, and the target directory to re-use build artifacts.

- the docker containers are removed when their execution finishes
  because it's no longer necessary to re-start them to inspect them
  because all the interesting output is in the outer target directory

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).

bc61db2e36 don't test always against gcc_s 
instead test half of the time against gcc_s and the other half test
against the native operation (\*).

(\*) Not all the targets have available a native version of the
intrinsics under test. On those targets we'll end up testing our
implementation against itself half of the time. This is not much of a
problem because we do several quickcheck runs per intrinsic.
