Leonardo Yvens 75406dd8ff Use transmute instead of casts In RuntimeValue conversion. (#102)
Casts have arithmetic semantics, and under some build configurations
Rust will panic when encountering an arithmetic overflow.
Use a transmute instead since it's what we mean.
The previous code worked, but still I added a test for good measure.

Remove old fixtures. (#54)
Remove all old test fixtures that migrated in this repo from the parity-wasm.

Also, use .wast files instead of compiled .wasm. I believe this is more convenient than testing a .wasm file and having a corresponding .wast file, which might go out of sync.
