Which, as I've realized only now, means the title should also say
SSE3 (also in patch 04, i.e. the series also completely covers that
ISA extension, except for testing, but I intend to only have another
set of tests for the full SSE3, SSE4{.1,.2,a} set, to somewhat limit
the bloat).

I've also dropped the stray h from the last four entries here.
