* values.c allocate_repeat_value): Allocate an array type, and
a value of that type; use that instead of setting VALUE_REPEATED.
* value.h (struct value): Remove fields repetitions and repeated.
(VALUE_REPEATED, VALUE_REPETITIONS): Removed, no longer used.
* c-valprint.c, ch-valprint.c, eval.c, printcmd.c, valops.c,
value.h, values.c: Simplify, since now VALUE_REPEATED is never used.
* valprint.c (value_print_array_elemen): Removed never-used function.
