c0ba4753eb Enable wasi-common by default (#177) 
This removes the --wasi-common, as it's now on by default, and adds a
--wasi-c option to enable the wasi-c implementation.

7ac6666fcb Fixes incorrect guest fd encoding 
Surfaced when running sunfishcode/misc-tests. When trying to
truncate the file without the __WASI_RIGHT_PATH_FILESTAT_SET_SIZE
right, error __WASI_ENOTCAPABLE was correctly returned, however,
the guest fd pointer was not encoded to -1 in that case. This
commit fixes it by taking out the guest fd encoding out of the
conditional branch which turns out obsolete.

`try_from` is stable now, so cast is unnecessary.

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.

06b6ec42b9 Provide the C WASI implementation as an option. 
This adds the C WASI implementation as a new crate, wasmtime-wasi-c,
and adds a command-line flag to the wasmtime command-line driver to
select which WASI implementation to use.

23055196fc Bump the minimum required Rust version to 1.34. 
1.34 was [released] on April 11, so it satisfies the stable Rust
[policy].

Notably, this version includes the new `try_from` features.

Now that `try_from` is in stable Rust, we can use it here.
