71c0142cd4 Rename the address field of Table/Memory/Global exports to definition. 
For functions, `address` makes sense because it's the address of the
function. Bt for Table/Memory/Global, it points to a `VM*Definition` field.

3f24098edc Implement the remaining valid spec tests. 
And lots of other miscellaneous changes. Rename InstanceWorld to
InstancePlus and reorganize its contents. This still isn't a great name,
but at least now it has a clear purpose.

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.
