Rename value categories to expression categories based on [Discord discussion](https://discord.com/channels/655572317891461132/753021843459538996/1092924035517665332) regarding naming and behavior. >* let expression -> value expression >* var expression -> reference expression >* located expression -> initializing expression >So: >- "value expressions" produce values (with no associated location). "reference expressions" produce a location of an existing value. "initializing expressions" take a location and initialize it. >- A let binding is initialized by a value expression, because lets represent values (with category conversions performed as needed, but if a conversion is performed from a different category of expression, the value of the object is pinned for the lifetime of the let). >- A var binding is initialized by an initializing expression, without performing a copy (with category conversions performed as needed, calling a copy constructor if the initializer is a different expression category). >- The & operator requires a reference expression, and it's an error to give it other kinds. >- The left-hand side of . requires a value expression when calling a function with a non-addr receiver, and requires a reference expression when calling a function with an addr receiver (it's an error to give it a value expression, and for an initializing expression, a temporary is materialized). Changes * Rename "value category" to "expression category" * Rename Var and Let value categories to Value, Reference, and Initializing expression * Rename `lvalue` to `location` (most of the time)
