Implement Pointers and References

Browse Source 
This change implements pointers and references as described by the WGSL
specification change in https://github.com/gpuweb/gpuweb/pull/1569.

reader/spirv:
* Now emits address-of `&expr` and indirection `*expr` operators as
  needed.
* As an identifier may now resolve to a pointer or reference type
  depending on whether the declaration is a `var`, `let` or
  parameter, `Function::identifier_values_` has been changed from
  an ID set to an ID -> Type* map.

resolver:
* Now correctly resolves all expressions to either a value type,
  reference type or pointer type.
* Validates pointer / reference rules on assignment, `var` and `let`
  construction, and usage.
* Handles the address-of and indirection operators.
* No longer does any implicit loads of pointer types.
* Storage class validation is still TODO (crbug.com/tint/809)

writer/spirv:
* Correctly handles variables and expressions of pointer and
  reference types, emitting OpLoads where necessary.

test:
* Lots of new test cases
