cb2eca0f91 Remove the program class. 
It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just
those two functions and make Execute and Wait implementations details.

654190a12d Add a boolean parameter to the ExecuteAndWait static function to indicated 
if execution failed.  ExecuteAndWait returns -1 upon an execution failure, but
checking the return value isn't sufficient because the wait command may
return -1 as well.  This new parameter is to be used by the clang driver in a
subsequent commit.

d5d0764b3b Have Program::Wait return -2 for crashed and timeouts instead of embedding 
info in the error message. Per Dan's request.

55aeb55aa3 Bugpoint support for miscompilations that result in a crash. 
This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.
