Detailed Description

A struct for encapsulating location information about an operator
and the operation built from it.

m_operator_loc is the location of the operator
m_combined_loc is the location of the compound expression.

For example, given "a && b" the, operator location is:
   a && b
     ^~
and the combined location is:
   a && b
   ~~^~~~
Capturing this information allows for class binary_op_rich_location
to provide detailed information about e.g. type mismatches in binary
operations where enough location information is available:

  arg_0 op arg_1
  ~~~~~ ^~ ~~~~~
    |        |
    |        arg1 type
    arg0 type

falling back to just showing the combined location:

  arg_0 op arg_1
  ~~~~~~^~~~~~~~

where it is not.
