7faa15d7ac More infrastructure. 
Improve handling of memory.grow/size, add a standalone wast runner,
test harness improvements.

83f8a31010 Convert the wast test harness into a crate. 
This uses a build.rs file to collect all the wast tests and create
individual `#[test]` lines for them, so that `cargo test` can run them
in parallel.

fe1643733b Remove use of offset_of! from wasmtime-environ. 
wasmtime-environ is meant to support cross compilation, so it shouldn't
have dependencies on target layout of structs. This moves the layout
back into wasmtime-execute, and adds a system of asserts for checking
that wasmtime-environ's offsets stay in sync.

8dbd4b8d7c Start a wast testing harness and add some tests. 
This implements a minimal wast testing harness in tests/wast.rs, which
runs the wast tests under tests/wast.

It also adds tests for trapping in a variety of ways, and fixes several
bugs exposed by those tests.

f44fe25f9c Rewrite linear memory handling in terms of simple mmap/VirtualAlloc. 
The memmap crate doesn't make it straightforward to have part of the
region be writeable and part readonly. Since this is a fairly boutique
use case, and we don't need all that much code, just use the low-level
APIs directly.

Also, introduce a concept of "tunables" for adjusting the parameters of
the runtime.

416f8c094d Name Table and Memory's initial field minimum and make it u32. 
The spec has switched to calling the "initial" field the "minimum" field
because when linear memory is imported, it may initially be greater than
the "initial" value.

Making it u32 instead of usize will help avoid accidental host-specific
behavior.
