4fef03f5f8 [meta] Legalization: remove spurious assert; 
This assert was added when porting legalization from Python to Rust and
doesn't hold when we have derived type variables.

102dbbb343 Bump the required rust version to 1.35. 
Rust 1.34 gets errors like this:

```
$ cargo +1.34.0 build --release
   Compiling cranelift-wasm v0.32.0 (cranelift/cranelift-wasm)
error[E0259]: the name `std` is defined multiple times
  |
  = note: `std` must be defined only once in the type namespace of this module

error: aborting due to previous error

For more information about this error, try `rustc --explain E0259`.
error: Could not compile `cranelift-wasm`.

To learn more, run the command again with --verbose.
```

Updating to Rust 1.35 fixes this.

b1488decc4 Only create copy_nop instructions for types for which an encoding exists. Issue #779. 
PR #773 detects, at reload time, `copy` instructions that copy a value from stack
slot back to the same stack slot.  It replaces them with `copy_nop` instructions
that have a null encoding (hence producing no code).

For x86_64, `copy_nop` encodings for the types I64, I32, F64 and F32 are
provided.  Unfortunately the code that detects the redundant copy doesn't
check the type of the copied value, hence leaving itself open to the danger of
creating a `copy_nop` instruction cannot be encoded (which is different from
saying it has a null encoding).

This patch:

* Expands the x86_64 set of `copy_nop` encodings to: I64 I32 I16 I8 F64 and F32

* Adds encodings for the same for x86_32, rv64 and rv32.

* In `visit_inst()` in `reload.rs`, checks the type of the copied value accordingly.

* Adds comments explaining the above.
