Add abbreviations for icmp/fcmp, store and br, which are the most common instructions that don't have abbreviations yet. This requies increasing the abbreviation size to 5 bits. This gives about 3-5% bitcode size reductions for the clang build: https://llvm-compile-time-tracker.com/compare_clang.php?from=d74d4ffa3342a97bcdfceae75616c755f83b3ca2&to=e8e45c235a7cd99269f45b86114245cca5da3dd8&stat=size-file&sortBy=absolute-difference
