When output range is only one entry, and input is low_pc/high_pc do not convert to ranges. This helps with size of .debug_ranges/.debug_rnglists. It also helps when either low_pc/high_pc is 0. We not generating potentially invalid ranges that result in LLDB error. Also fixed handling of DW_AT_subprogram with ranges. This can be created with -fbasic-block-sections=all.
