This file handles the generation of rtl code from tree structure
above the level of expressions, using subroutines in exp*.c and emit-rtl.cc.
The functions whose names start with `expand_' are called by the
expander to generate RTL instructions for various kinds of constructs.   
Functions and data structures for expanding case statements.   
Case label structure, used to hold info on labels within case
  statements.  We handle "range" labels; for a single-value label
  as in C, the high and low limits are the same.

  We start with a vector of case nodes sorted in ascending order, and
  the default label as the last element in the vector.

  Switch statements are expanded in jump table form.
