Eric Christopher cad9b53c02 Add a name for the anonymous type we're creating for subrange 
types and a FIXME for what we should be doing. Should solve the
immediacy of PR12069 where our debug info is crashing another
tool.

Bill Wendling d7767125d5 Use the 'count' attribute to calculate the upper bound of an array. 
The count attribute is more accurate with regards to the size of an array. It
also obviates the upper bound attribute in the subrange. We can also better
handle an unbound array by setting the count to -1 instead of the lower bound to
1 and upper bound to 0.

Bill Wendling bfc0e5725f Add a 'count' field to the DWARF subrange. 
The count field is necessary because there isn't a difference between the 'lo'
and 'hi' attributes for a one-element array and a zero-element array. When the
count is '0', we know that this is a zero-element array. When it's >=1, then
it's a normal constant sized array. When it's -1, then the array is unbounded.
