  [Bitcode] Add abbreviations for additional instructions (#146825)

Add abbreviations for icmp/fcmp, store and br, which are the most common
instructions that don't have abbreviations yet. This requires increasing
the abbreviation size to 5 bits.

This gives about 3-5% bitcode size reductions for the clang build.
