07f19a085d [torque] implement function pointers to builtins 
This CL adds the new type expression
builtin(Context, ArgType1, ...) => ReturnType
and allows to use Torque-defined builtins as values of this type, as well
as calling values of this type.
The new function pointer types are subtypes of Code.

3d2cb0b4ae [torque]: Implement Generics for Builtins and Macros 
Including specialization, e.g.:

  // Declare parameterized generic
  macro GenericMacroTest<T: type>(param: T): Object {
    return Undefined;
  }

  // Declare specialization of generic
  GenericMacroTest<Object>(param: Object): Object {
    return param;
  }

  ...
  assert(GenericMacroTest<Smi>(0) == Undefined);
  assert(GenericMacroTest<Smi>(1) == Undefined);
  assert(GenericMacroTest<Object>(Null) == Null);
  assert(GenericMacroTest<Object>(False) == False);
  ...

Known issue: specialization doesn't rigorously checked to verify
that specialization signature precisely matches generic declaration.

a410e9e441 [torque] Emit labels only if they are used. 
This CL changes the generated C++ code for LabeledStatementBlocks to
only emit labels if they are used.

Prior to this CL, when a label was only used on one path of an
if constexpr expression, and not at all anywhere else,
the try/label construct would BIND a label that was not used,
causing a CSA verification error.

5f920f770d [torque]: Add the ability to test Torque functionality with cctest 
In the process, add a few simple tests for "constexpr" expressions, which
identified a few bugs that are also fixed in this CL.
