Implemented the usage of DW_AT_ranges for non-contiguous address ranges.
The gcc produces DW_AT_ranges for non-contiguous address ranges, like
compilation units containing functions which are placed in different
ELF-sections or lexical scopes that are split up. With this commit
CompCert also uses this DWARF v3 feature for gnu backend based targets.
In order to ensure backward compability a flag is added which avoids
this and produces debug info in DWARF v2 format.
Bug 17392.
