Add ProgramExitedNonzero argument to executeProgram(), and make it
tell its caller whether the program exited nonzero.

Move executeProgramWithCBE() out of line, to ExecutionDriver.cpp, and remove
its extra arguments which are always defaulted.  Make it turn off
check-exit-code if the program exits nonzero while generating a reference
output.

Make diffProgram() assume that any nonzero exit code is a failure, if
check-exit-code is turned on.

This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.

that defines the symbol "main."  This is a hack that ensures that programs
that place their main function in a library and then link it in
(i.e. Apache 2.x) get their main function linked in.

There is probably a more correct way to do this, but this works for now.

New command line parsing. This isn't as perfect as I would have liked. The CommandLine Library needs to be extended, in order to parse the options and allow for optional dashes. In addition, the help option isn't correct since I do the parsing mostly myself. But this is in the ocorrect ar format.
