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.

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.

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.

and thus predictable dump names within selftests.

This patch extends update-quadmath.py to update fmaq from glibc.

The issue in that function was that quadmath-imp.h had a struct in a
union with mant_high and mant_low fields (up to 64-bit) whereas glibc
has mantissa0, mantissa1, mantissa2 and mantissa3 (up to 32-bit).  The
patch changes those fields to be the same as in glibc, moving printf /
strtod code that also uses those fields back to closer to the glibc
form.  This allows fmaq to be updated automatically from glibc (which
brings in at least one bug fix from glibc from 2015).

nanq was also using the mant_high field name, and had other issues: it
only partly initialized the union from which a value was returned, and
setting mant_high to 1 meant a signaling NaN would be returned rather
than a quiet NaN.  This patch fixes those issues as part of updating
it to use the changed interfaces (but does not fix the issue of not
using the argument).

Bootstrapped with no regressions on x86_64-pc-linux-gnu.
