Enum llvm_bitcode::bitstream::BuiltinAbbreviationId

#[repr(u64)]pub enum BuiltinAbbreviationId {
    EndBlock,
    EnterSubBlock,
    DefineAbbreviation,
    UnabbreviatedRecord,
}

An abbreviation id is a fixed-width field that occurs at the start of abbreviated data records and inside block definitions.

Bitstream reserves 4 special abbreviation IDs for its own bookkeeping.
