fdcb2184a8 Support 32-bit build. (#44) 
* Support 32-bit build.

Signatures/functions/imports/exports etc are defined as varuint32 in
the WebAssembly specification so use u32 rather than u64.

Decrease the static memory constants for 32-bit addressing mode so
that they fit within 32-bit memory constraints.

Conditionalize cmake compile of SignalHandlers.cpp so that -m32 is
passed when building 32-bit.

Add a no-op match for Reloc::X86CallPCRel4 during linking. This is
probably the wrong thing, but it allows the tests to pass. Using the
same logic from the Reloc::X86PCRel4 case did not work.

00a4e93bcd Add a concept of "global exports". 
This adds a feature which allows one to look up an export by name
without knowing what module it's in -- `lookup_global_export` on an
`InstanceContents`.

The main expected use for this is to support APIs where module A
imports a function from module B, and module B needs to access module
A's memory. B can't import it from A in the normal way, because that
would create a dependency cycle. So for now, allow B to look up A's
exported memory dynamically with `lookup_global_export`.

In the future, with reference types and possibly host bindings, we'll be
able to pass references to memory as arguments, which will obviate the
need for this mechanism.

dae04be948 Switch from hashmap_core to hashbrown. 
As suggested
[here](https://github.com/Amanieu/hashmap_core/pull/10#issuecomment-455866083).

This also allows us to re-enable the basic compile fuzz target.
