d162f8bc59 Implement Abs8 relocations, and fix X86PCRel4 relocations. 
With new versions of cretonne-codegen:

 - Non-colocated calls are emitted as a movabs with an indirect call.
   This uses an Abs8 relocation.

 - Colocated calls are emitted as direct calls, but the "+ 4"
   adjustment is now folded into the addend, so we don't need to
   handle it explicitly in the X86PCRel4 code anymore.

9d41135fe3 Translate from function-body index to function-index-space index. 
The wasm function index space consists of the index space of the
imported functions concatenated with the index space of the defined
functions. When iterating through function definitions, it's necessary
to adjust the index when a function-index-space index is needed.

5a5f4e4a2f Switch to published packages rather than straight git paths. 
We can do this now that all our dependencies are available in published
form, and this should reduce accidental breakage which APIs change.

114da83ad6 Avoid using to_string() on ExternalName to create strings for symbol names. 
ExternalName's `to_string()` prepends a '%' for Cretonne's text syntax,
but for creating symbol names we just want the raw bytes.

b87178647b Change get_func_type's return type to SignatureType. 
It's the same thing, but provides more readability.

ca1b461375 Begin internal reorganization. 
This begins reorganizing how translation and compilation occur, and
setting up infrastructure for imports/exports and relocations. It
splits parts out of StandaloneRuntime, forming Module, Compilation,
and Instance structs, which can be used more independently.

It also simplifies the command-line interface, in a step towards
making simple tools that just expose the functionality of the
libraries.

9f7d0a659c Use VmCtx arg for globals, and a global for the heap. 
This replaces the ReservedReg strategy, and is more flexible.

ecd746718b Remove comments about manually saving callee-saved registers. 
Even though Cretonne doesn't implement callee-saved registers yet,
it will, so we shouldn't need manual save/restore code when calling it.

d0fe50a2a8 Check in the wasmstandalone code. 
This is based on the code in https://github.com/denismerigoux/cretonne/commits/wasm2cretonne
before wasmstandalone was removed, with minor updates for the new library structure.
It is not yet updated for the latest cretonne API changes.
