i965/fs: Check for compilation failure and bail before optimizing.
Prior to this patch, it would attempt to optimize and allocate registers for the program even if it failed to compile. This seems wasteful. More importantly, the "message length > 11" failure seems to choke the instruction scheduler, making it somehow use an undefined value and segmentation fault.
