ca2fdc5ccb Update no_std support. 
This `no_std` support isn't complete though, as some dependencies
don't support it.

7592c99f3b Refactor the compilation and instantiation pipeline. 
wasmtime-execute is now wasmtime-jit. Move `JITCode` and the TargetIsa
into a new `Compiler` type. `InstancePlus` is no more, with trampoline
functionality now handled by `Compiler`.

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.

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.

da4382802a Add a LICENSE file to published crates. 
The individual crates are published separately from the main repository
on crates.io. To ensure that a copy of the LICENSE file accompanies all
published copies of the code, give each crate its own LICENSE file.

fb7153ccf4 Update to cranelift 0.20.0. 
The biggest change is the split from FunctionIndex to
DefinedFuncIndex to FuncIndex. Take better advantage of this by
converting several Vecs to PrimaryMaps.

Also, table_addr can now handle indices of the table index type,
so we don't need to explicitly uextend them anymore.
