DW_FORM_data8

[Richard Henderson <rth@redhat.com>]

The dwarf2 reader doesn't believe that DW_FORM_data8 holds
a constant value.  Fixed thus.

Ok?

PS: Not sure what generated this form -- certainly gcc should be
emitting the smaller forms when the array bounds allow.  Perhaps
it's output from an older gcc...  Anyway, it shows up on an ia64
installation I have here.


	* dwarf2read.c (read_array_type): Accept DW_FORM_data8 as
	a constant array bound.
