Kyle Evans c79cee7136 kernel: provide panicky version of __unreachable ... __builtin_unreachable doesn't raise any compile-time warnings/errors on its own, so problems with its usage can't be easily detected. While it would be nice for this situation to change and compilers to at least add a warning for trivial cases where local state means the instruction can't be reached, this isn't the case at the moment and likely will not happen. This commit adds an __assert_unreachable, whose intent is incredibly clear: it asserts that this instruction is unreachable. On INVARIANTS builds, it's a panic(), and on non-INVARIANTS it expands to __unreachable(). Existing users of __unreachable() are converted to __assert_unreachable, to improve debuggability if this assumption is violated.
