[PATCH] Fix PR69537

I am fixing the missed optimization / bogus warning with relaxing the guard around "old" fold_{widened,sing_changing}_comparison which is now in match.pd. Bootstrap and regtest running on x86_64-unknown-linux-gnu. I'm curious if any issues with casts-to-BOOLEAN_TYPE show up in our testsuite

[PATCH] Fix PCH on systems where stdc-predef.h includes other headers (PR pch/68176)

Hi! As mentioned in the PR, most of the pch tests fail if stdc-predef.h header includes other headers. I don't have such a system, but changed my stdc-predef.h to include a dummy header bits/predef.h and this patch fixes all the tests that failed because of that. AFAIK file->implicit_preinclude

RFA (tree.h): C++ PATCH for c++/67407 (ICE with protected access)

In this testcase, the problem was that we were checking DERIVED_FROM_P, which uses dfs_walk_once and thus BINFO_MARKED, in the middle of a dfs_walk_once_accessible, which also uses BINFO_MARKED, and the marks from one walk were confusing the other walk. Fixed by moving these binfo walking
