Minimized test case.
Switched to canonical crash case naming: [nnn]-[normalized-crash-function].[suffix]

The normalized-crash-function is generated using:

  xcrun swiftc -o /dev/null example.swift 2>&1 | egrep 0x | \
    egrep -v '(PrintStackTrace|SignalHandler|_sigtramp)' | \
    head -1 | awk '{ print $4 }' | cut -f1 -d"(" | \
    sed "s/[^a-zA-Z]/_/g" | tr "[A-Z]" "[a-z]" | sed 's/_*$//g' | \
    sed 's/^_*//g' | sed 's/__*/_/g' | tr "_" "-"
Removed logs.
Updated to reflect new naming.
New stack trace files.
