Sourcetrail fails to find implicit destructor calls

[petermost]

Copied from Sourcetrail issue: CoatiSoftware#839

Sourcetrail does not appear to find implicit destructor calls.

Being able to find destructor calls would be immensely helpful.

In the mean time, at the least it would be helpful for Sourcetrail to provide a warning message that it does not expect to find them.

@catskul: The current indexer only uses the Clang AST, which doesn't provide that information.
This Stackoverflow answer "How to get information about call to destructors in Clang LibTooling?" shows that it is necessary to use the 'Control Flow Graph' (CFG) to retrieve that information.

Added with commit 0beeaa0

Please note:

• Only non-trivial destructors are being indexed, because only those are detectable via CFG.
• The source code location of the destructor call is always at the end of the function, because the CFG doesn't offer locations.

Maybe @mlangkabel or @egraether have a better idea, but they probably don't have time to support a Sourcetrail clone.

Disabled the detection/indexing of the destructor calls with commit bccad3b because of a crash (assertion) in CFG::buildCFG

[petermost]

Re-enabled the detection/indexing of non-trivial destructor calls, now that Clang-18 is being used.
