Dumping the type right before it crashes shows
BuiltinType 0x55853bdd30e0 '_Bool'

I've been unable to manually repro with _Bool in a small C/C++ example, which seems to map to normal bool.

Probably similar to #58135? @DavidSpickett

Looks like it crashes on:

VarDecl 0x4ec36e380 <<invalid sloc>> <invalid sloc> NotADL 'const clang::CallExpr::ADLCallKind' static cinit
`-IntegerLiteral 0x4ec36e3f0 <<invalid sloc>> 'bool' 0

[Michael137]

Shorter repro:

$ cat enum.cpp 
struct S {
    enum class ADLCallKind : bool { NotADL, UsesADL };
    static constexpr ADLCallKind NotADL = ADLCallKind::NotADL;
    static constexpr ADLCallKind UsesADL = ADLCallKind::UsesADL;
};

int main() {
    S s;
    return 0;
}

$ ./bin/lldb a.out
(lldb) im loo -t S
Unexpected type for integer literal!

Will probably need to extend what David did for bool initialisation in DWARFASTParserClang to bool enum types too
