Prevent assert at frame.c, l. 6311 by initializing glyph cachels.
* frame.c (Fmake_frame): Ensure that reset_glyph_cachels gets called.
(setup_minibuffer_frame): Improve header comment.
* redisplay.c (redisplay_window): Update comment.
Remove code checking for uninitialized face_cachels and glyph_cachels.
Can't happen in theory, and guarded by asserts in practice.
* window.c (allocate_window): Update comment on reset_*_cachels.
