39fb7618e4 * WebAssembly internal linker: refactored the writing of the memory section and 
the memory import section: introduced a TWasmMemoryType record, and structures
  for holding the memory entries in the import and memory sections, instead of
  writing them in an ad hoc manner. The memory information in the linker map
  file is now also a little more detailed.

b9ca30165c * WebAssembly: refactored tai_local, so that it is a single directive, 
containing multiple locals, instead of creating multiple tai_local directives,
  each containing a single local. No functional changes.
