[llvm-testresults] bwilson__llvm-gcc_PROD__i386 nightly tester results

[Bob Wilson]

Not only did yesterday's 14% regression on SingleSource/Benchmarks/McGill/chomp not go away, but now we have new problems:
<rdar://problem/8820549> 28% performance regression on i386 Dhrystone

I realize now that I probably should have made an llvm.org PR for that instead of an Apple-internal radar report.  If anyone outside Apple wants to investigate, I can do that.  Otherwise, I'll just try to remember to do it next time....
