Debugger can't handle map comprehensions

[ecpeterson]

Describe the bug
The Debugger crashes when loading a file with a map comprehension. Map comprehensions show up as {mc, ...} tuples, for which there's no entry in this case expression.

To Reproduce
Compile, load, and inspect a module with a map comprehension in it.

Expected behavior
I expected the Debugger to at least load the file, even if its ability to manipulate it was diminished.

Affected versions
I checked this only with OTP 26.0. I also looked at the main branch in the source tree, where the bug appears to still be present.

Thanks! A fix will be included in OTP 26.2.
