Global: Use of "Program" vs "Assembly"

There has been an effort on the latest draft to remove the use of the word "assembly" and replace it with "program", for example:
- see section 7.7.3 where "internal" and "protected internal" are used.
- see section 8.4.5 for a rename
- see section 8.4.5.6 for string equality.

Access limited to this program, which is incorrect, because the scope is really limited to an assembly.
