PR analyzer/93307 reports that in an LTO bootstrap, there are ODR
violations between:
- the "region" type:
gcc/analyzer/region-model.h:792
vs:
gcc/sched-int.h:1443
- the "constraint" type:
gcc/analyzer/constraint-manager.h:121
vs:
gcc/tree-ssa-structalias.c:533
This patches solves this clash by putting all of the analyzer names
within a namespace. I chose "ana" as it is short (to save typing).
The analyzer selftests are moved from namespace "selftest" to
"ana::selftest".
There are various places where the namespace has to be closed
and reopened, to allow e.g. for specializations of templates
in the global namespace.

The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs.
