This CL removes the code specialization for WASM functions that access
globals. Previously, we were embedding the start address of the globals
memory (globals_start) as a constant in the code, which required
patching for every instance. We now put this base in to the WasmContext,
which is available as a parameter to every WasmFunction.

We were looking at the unreachable flag or stack_depth of the target frame
instead of the current one in a couple of places (most notably BreakTo).
This change fixes these bugs and makes us pass the latest spec tests for
br_table validation. Also need to ensure that br_table targets have consistent
types, which is not implied if the stack is polymorphic.

This is more renaming work to comply with the naming in the public
design repository. E.g. types are called "value types" and we no longer
refer to ASTs.

Imports and exports in 0xC can be much more than functions, including
tables, memories, and globals. This CL refactors the underlying
organization of imports and exports to support these new import types.
