* Inserts a breakpoint instruction into the code.
*
* On architectures which support it, this is implemented as a soft interrupt
* and on other architectures it raises a `SIGTRAP` signal.
*
* `SIGTRAP` is used rather than abort() to allow breakpoints to be skipped past
* in a debugger if they are not the desired target of debugging.
