7120633363 Change the elems parameter of declare_table_elements to a boxed slice. 
Implementations that want a full `Vec` can use `into_vec` to convert it
back.

054e6fcf07 Add functions to ModuleEnvironment to support reserving buffers up front. 
These default to doing nothing, but implementations can override them to
preallocate buffers.

Also, reorder the functions in `ModuleEnvironment` to more closely
reflect the sequence from the WebAssembly module layout.

7f250e340c Simplify ModuleEnvironment. 
Remove some unneeded functions, and remove the `GlobalInit` special case
for data and elem initializer offsets; implementations that want that
information can provide it for themselves.
