When comparing dumps from compilations with debugging information generation
enabled and disabled, like for -fcompare-debug, commonly dump files generated
with TDF_NOUID are used. However, as has become painfully clear while
debugging
PR44832, such dumps do not help to spot the point where the DECL_UID ordering
of declarations / labels varies.
There should be a flag to request an enumeration of all declarations / labels
of each function to be dumped in the order of their DECL_UID as part of the
debugging dump for the function.
Also, a dump of FREE_SSANAMES can be useful at times.
