Make putting a breakpoint on the first instruction of a program work.

Previously a breakpoint at the first instruction would force us to
single-step.  Depending on the single-step implementation this would make us
step over the breakpoint and continue in many cases.  Fix this by passing the
address of the current instruction pointer which will skip the code that
checks if we need to step over a breakpoint.  A similar fix has been made
upstream many moons ago.  Fixes debugging static PIE on sparc64 and probably
others that use some sort of software single-stepping.
