Clang vendors may need to set a custom message for bug reports if the default
is not sufficient (e.g. if they need the user to provide more information than
what the default message asks for). This can be configured using the new macro
`CLANG_CUSTOM_BUG_REPORT_MSG`.

Subject: [PATCH] [clang] Allow custom bug report messages
Clang vendors may need to set a custom message for bug reports if the
default is not sufficient (e.g. if they need the user to provide more
information than what the default message asks for). This can be
configured using the new macro `CLANG_CUSTOM_BUG_REPORT_MSG`.
