Fix several clang static analyzer dead store warnings. * src/autofit/afhints.c (af_glyph_hints_reload, af_glyph_hints_align_weak_points): Remove unnecessary assignments. * src/bdf/bdflib.c (bdf_font_load): Ditto. * src/pshinter/pshalgo.c (psh_glyph_compute_extrema, psh_glyph_interpolate_other_points): Ditto. * src/type1/t1load.c (T1_Set_MM_Blend): Ditto.
