compiler: avoid GCC middle-end control warnings
GCC has started emitting "control reaches end of non-void function"
warnings. Avoid them for Go by 1) marking the builtin function panic
and the compiler-generated function __go_runtime_error as not
returning and 2) adding a default case to the switch used for select
statements that simply calls __builtin_unreachable.
Fixes golang/go#22767
Reviewed-on: https://go-review.googlesource.com/80416
* go-gcc.cc (Gcc_backend::Gcc_backend): Define
__builtin_unreachable.
(Gcc_backend::function): Add does_not_return parameter.
