Import only one module per line in the modules of the compiler

Browse Source 
Estimated hours taken: 3
Branches: main

compiler/*.m:
	Import only one module per line in the modules of the compiler
	where my previous diff did not already do so.

	Misc other cleanups.

	Where relevant, use the new mechanism in tree.m.

compiler/tree.m:
	Fix a performance problem I noticed while update :- import_module
	items. Instead of supplying a function to convert lists of trees
	to a tree, make the tree data structure able to hold a list of
	subtrees directly. This reduces the number of times where we have to
	convert list of trees to trees that are sticks just to stay within
	the old definition of what a tree is.
