// This class represents a single trace of LLVM basic blocks.  A trace is a
// single entry, multiple exit, region of code that is often hot.  Trace-based
// optimizations treat traces almost like they are a large, strange, basic
// block: because the trace path is assumed to be hot, optimizations for the
// fall-through path are made at the expense of the non-fall-through paths.
