Re: [r15-5359 Regression] FAIL: g++.dg/tree-ssa/pr109442.C -std=gnu++26 scan-tree-dump-not optimized "_M_start" on Linux/x86_64

[Sam James via Gcc-regression]

I think this testcase was accidentally included in
r15-5359-gcc33f880e553d1 but this problem can be ignored, as it is now
fixed by r15-5361-gaac5c57ee16723.

(TL;DR: just a git snafu and the problem is resolved AFAICT.)
