[google gcc-4_8] LIPO: check the incompatibility of use and saved command line


Hi,

This patch adds an extra check of the incompatibility of use and saved
command line for the primary module. If the check files, we skip the
inclusion of all aux modules.
Maybe we should check the aux module command line with the
use-compilation command line directly. But I keep the old way that
checks b/w saved command lines.

Tested with the program exposed this issue and internal benchmarks.
This check never failed for instrumentation based lipo in the test.

Thanks,

-Rong
