Allow instance allocators control over module compilation.

Browse Source 
This commit introduces two new methods on `InstanceAllocator`:

* `validate_module` - this method is used to validate a module after
  translation but before compilation. It will be used for the upcoming pooling
  allocator to ensure a module being compiled adheres to the limits of the
  allocator.

* `adjust_tunables` - this method is used to adjust the `Tunables` given the
  JIT compiler.  The pooling allocator will use this to force all memories to
  be static during compilation.
