Akira Hatanaka 2604830aac Add support for __builtin_verbose_trap (#79230) ...

The builtin causes the program to stop its execution abnormally and
shows a human-readable description of the reason for the termination
when a debugger is attached or in a symbolicated crash log.

The motivation for the builtin is explained in the following RFC:

https://discourse.llvm.org/t/rfc-adding-builtin-verbose-trap-string-literal/75845

clang's CodeGen lowers the builtin to `llvm.trap` and emits debugging
information that represents an artificial inline frame whose name
encodes the category and reason strings passed to the builtin.
