ipa-inline.c/tree-inline.c: port from fprintf to dump API (PR ipa/86395)

This patch ports various fprintf calls in the inlining code to using
the dump API, using the %C format code for printing cgraph_node *.
I focussed on the dump messages that seemed most significant to
end-users; I didn't port all of the calls.

Doing so makes this information appear in -fopt-info and in
optimization records, rather than just in the dump_file.

It also changes the affected dumpfile-dumps from being unconditional
(assuming the dump_file is enabled) to being guarded by the MSG_*
status. Hence various tests with dg-final scan-*-dump directives
need to gain "-all" or "-optimized" suffixes to -fdump-ipa-inline.

The use of %C throughout also slightly changes the dump format for
several messages, e.g. changing:

Inlining void inline_me(char*) into int main(int, char**).

to:

../../src/gcc/testsuite/g++.dg/tree-ssa/inline-1.C:13:8: optimized: Inlining void inline_me(char*)/0 into int main(int, char**)/2.

amongst other things adding "/order" suffixes to the cgraph node
names.

Support %f in pp_format

Numerous formatted messages from the inliner use %f, mostly as %f, but
occasionally with length modifiers.

This patch implements the simplest case of "%f" for pp_format (with no
modifier support) to make it easier to port these messages from fprintf
to dump_printf_loc.

The selftest has an assertion that %f on 1.0 is printed as "1.000000".
This comes from the host's sprintf, and I believe this is guaranteed by
POSIX: "If the precision is missing, it shall be taken as 6". If this is
an issue I can drop the selftest.

* c-format.c (gcc_dump_printf_char_table): Add entry for %f.

dump_printf: add "%C" for dumping cgraph_node *

This patch implements support for %C in dump_printf for dumping

(I would have preferred to have a code for printing symtab_node *

cgraph: add selftest::symbol_table_test

This patch adds a selftest fixture for overriding the "symtab" global,
so that selftests involving symtab nodes can be isolated from each
other: each selftest can have its own symbol_table instance.

In particular, this ensures that nodes can have a predictable "order"
and thus predictable dump names within selftests.
