Richard Smith e0c90767be Support for templated impl declarations (#2700) 
The strategy that we use for now to support template instantiation is to check the impl declaration as if it were a generic, but to defer all checking of the impl definition until we see a use in which all template parameters have arguments. At that point, we clone the impl definition and type-check the whole thing, with constant values set on the template parameters corresponding to the given arguments.

No caching of template instantiations is performed yet; each time we form a reference to a template instantiation, we instantiate it afresh. We also don't implement the name lookup rule from #949 yet; lookups during template instantiation look only in the actual type and not in the constraint.

Depends on #2699

Richard Smith 782bd87316 AST cloning mechanism (#2699) 
This is intended to be used for template instantiation, but for now takes no stance as to what it's cloning.

This is tested by parsing and cloning all of our test files, and checking that the result of converting each AST to proto is the same as the result of cloning and then converting each AST to proto.

Darshal Shetty e4a2d0f047 Addr Keyword Implementation (#1255) 
* Implement addr keyword

* Add files that were deleted during merge

Some files got deleted during merging trunk because of the executable
semantics rename.

* Implement changes from code review.

Major changes:
- Rename AddrBindingPattern to AddrPattern
- Fix AddrPattern related changes in fuzzing

* Update documentation for GetField

* Fix AddPattern according to @zygoloid's suggestions

* Apply @zygoloid's changes to method comment

* Add a multi-component field example

* Incorporate AST changes to fuzzer corpus

* Refactor the deduced_param_list grammar rule

Richard Smith 4cf7ed4f12 Rename some classes to match the design better (#1287) 
* `FieldAccessExpression` -> `SimpleMemberAccessExpression`
    * Member `aggregate` -> `object`
    * Member `field` -> `member`
* `CompoundFieldAccessExpression` -> `CompoundMemberAccessExpression`
* `GetField` -> `GetMember`

As discussed in #1233.

Richard SmithandJon Meow c29f56e667 Initial support for generic parameters that are introduced in a function parameter list (#1247) 
In order for this to work, we need to always use the argument deduction code path for function calls, instead of only using it when there is a `[...]` list, which means that argument deduction now needs to support implicit conversion.
