[RFC PATCH v1 12/23] LoongArch: bug: Add reachable annotation to warning macros

[Youling Tang]

WARN* and BUG* both use `break 0x1` opcodes and the distinction is
provided by the contents of the bug table. This table is not accessible
to objtool, so add an annotation to WARN* macros to let objtool know
that break handler will return an resume the execution of the instructions
following the WARN's break.
