This reorders the common and c++ global tree arrays. It introduces a
module-specific High Water Mark, below which are the immutable slots
initialized at startup and beyond which are the lazily filled slots
(and a few immutables we need to locate by name lookup anyway).

We directly reference global trees, and expect them to be immutable.
This reorders the global tree arrays, moving the mutable ones after a
High Water Mark. Those after the HWM are not directly accessed in the
module machinery (we'll reference by name or equivalent).

This patch neatens up the recent change in except.c to register GTY
roots. I've made them all global trees.
Whilst there I noticed except's declare_library_fn could be doing more
work, rather than its callers repeat themselves. Also renamed a couple
of global trees to be more mn

More global trees.
* cp-tree.h (enum cp_tree_index): Add CPTI_GLOBAL,
CPTI_GLOBAL_TYPE, CPTI_GLOBAL_IDENTIFIER, CPTI_ANON_IDENTIFIER,
CPTI_INIT_LIST_IDENTIFIER.
(global_namespace, global_type_node, global_identifier,
