Added crash cases:
* crashes/0325-global-is-external.swift
* crashes/0326-llvm-constantexpr-getgetelementptr.swift
Marked 0281 and 0312 as duplicates.
Fixed command line parsing bug. Now re-running compiles to catch intermittent crashes.
Fuzzing Friday 2014-10-17: 988 new compiler crashes added.

This is a new record thanks to a brand new Markov Chain based fuzzer. Also new this week is the use of an efficient crash case minimizer which automatically shrinks the crash cases found by the fuzzer.

Previous Fuzzing Fridays:
* 2014-10-10: 50 crashes added.
* 2014-10-03: 25 crashes added.
* 2014-09-26: 49 crashes added.
Removed non-crash.
Limit stack trace logging to swift/llvm function to avoid noise.
Re-run stack trace logging with non-swift/llvm functions removed.
Removed stack traces using old numbering (%03d instead of %04d).
Filtering out llvm::sys::PrintStackTrace and SignalHandler(int) since these are present in all stack traces.
Updated example output.
Xcode 6.1 (6A1052d) fixed 0 % of all open Swift crashing bugs (0 of 25 crashes).
