Originally this test case tested the specified behavior (that -gmlt
would not produce DW_AT_ranges and that when no CU DW_AT_ranges were
produced, no debug_ranges section (not even an empty list) would be
produced) but then the ranges emission code was improved not to create
ranges of a single element (instead favoring high_pc/low_pc) and so this
test case no longer exercised the -gmlt portion of the behavior.
This caused me some confusion when reading the comments and trying to
update this test case for future changes to -gmlt. I've made this test
resilient to those changes (by using the {{DW_TAG|NULL}} pattern to
block the end of the attribute search at the end of the CU's attribute
list without mandating that it must (or must not) be followed by another
tag (the future changes to -gmlt should produce no subprograms in this
CU))
Fix the test case to have two functions in distinct sections to force
the use of DW_AT_ranges.
