* Add ARMv7 as CI test target

* Avoid UB in conversions from floating point

When truncating floating point values to integer values, we need to
avoid undefined behavior if the argument does not fit into the target
type which is currently impossible using casts of primitive types.

Hence, this reimplements those conversions using arbitrary precision
integers and rationals from the num crate.

adam-rhebo 8dac328ea7 Remove hashbrown and use BTree{Map,Set} from the alloc crate (#187)
* Remove hashbrown and use BTree{Map,Set} from the alloc crate

wasmi-validation must handle untrusted input and hence we switch from
Hash{Set,Map} (whether std's or hashbrown's) to BTree{Set,Map} to avoid
algorithmic complexity attacks while retaining no_std support.

Closes #183

* Improve memory locality of checking for duplicate exports

Using a sorted slice gives us the same O(N log N) worst case execution
time as using a BTreeMap, but using a single allocation as with HashMap,
so that we should see better memory locality and hence better constant
factors when checking for duplicate exports.

Move spec testsuite into tests. (#56)
Move all spec testsuite into `/tests` directory.

So it means that several changes will happen:

- Compilation will share common dependencies in target directory. This should make CI builds faster. This also should reduce space requirements.
- Common Cargo.lock file
- `cargo test` will include spec tests.
- `cargo check --tests` will also include spec tests.
