Seems the performance degradation that started with
r5-5019-g27d93d2c8a36cea495599e4eb070d3f922aab279
is gone on the trunk with the
r11-3300-g83e037364e0d6dd74d595751e8bc8c461b4cb8fa
change.
Haven't tried 4.4 though.

Tried that now and I don't see any slowdown in between gcc 4.4 branchpoint -
tried r145106 in particular - and r217669 when using the 4.4 preprocessed
source, so I bet but can't prove easily is that it is the r203035 changes which
are essential for the other PR. So marking as fixed in GCC 11.

Changing component to middle-end, since neither the regression nor the fix was
a change to libstdc++ code.
