Use the program counter to determine the contents and size of a
breakpoint instruction. It returns a pointer to a string of bytes
that encode a breakpoint instruction, stores the length of the string
to *@var{lenptr}, and adjusts pc (if necessary) to point to the actual
memory location where the breakpoint should be inserted.

Although it is common to use a trap instruction for a breakpoint, it's
not required; for instance, the bit pattern could be an invalid
