[Bug other/13756] [tree-ssa] documentation missing in the internals manual

Here are additional comments after reading the GCC Internals manual from the tree-ssa branch. 
Although Chapter 7 describes the high-level process of going from language-specific trees to GENERIC, 
then lowering to GIMPLE and finally going through the various SSA and non-SSA passes
is described in sufficient detail, there is no information on the GENERIC and GIMPLE representations 
themselves.

Chapter 8 describes C and C++ front end specific trees, but there is a complete disconnect with tree-
ssa. This chapter needs to be changed to reflect the situation in the tree-ssa branch.

Chapter 9, which deals with analysis and optimization of GIMPLE trees starts with a small introduction 
that refers to "the chapter describing GENERIC and GIMPLE" for more details. Such a chapter is much 
needed, especially since one of the stated goals of tree-ssa is to improve maintainability.
