Some unit tests use code from training. Those tests are enabled
if training is enabled, so for that case the "check" target
depends on the "training" target.

tesstrain_utils.sh sets the shell flag -e, so it exits immediately
if a command exits with a non-zero status.
The following command returns a non-zero status as soon as counter is a
multiple of par_factor (par_factor=8, that means as soon as 8 fonts or
images are processed):
let rem=counter%par_factor
The new code fixes this undesired exit.

pango_coverage_get and pango_coverage_unref should not be called
with coverage == nullptr.
pango_font_get_coverage should not be called with font == nullptr.
Otherwise Pango prints runtime error messages:
(process:12657): Pango-CRITICAL **: pango_coverage_get: assertion 'coverage != NULL' failed
(process:12657): Pango-CRITICAL **: pango_coverage_unref: assertion 'coverage != NULL' failed
(process:12657): Pango-CRITICAL **: pango_font_get_coverage: assertion 'font != NULL' failed
(process:12657): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
Typically those errors occur if a required font is not installed,
so this can be a quite common error.
Fix also a potential resource leak in PangoFontInfo::CoversUTF8Text.

Commit d36231e3e4 did not distinguish
between AVX and AVX2, so AVX2 code was enabled for IntSimdMatrix
even when only AVX was supported.
This resulted in an illegal instruction.
