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.
