Don't test for ASM output but for IR output. llvm-svn: 169232

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. llvm-svn: 169219

Simplify/generalize some debug info test cases Mostly, try to depend on the annotation comments more so these tests are more legible, brief, and agnostic to schema changes in the future (sure, they're not agnostic to changes to the comment annotations but since they're easier to read they should be easier to update if that happens). llvm-svn: 177457
