This matches the terminology in the spec, and it avoids confusion with the function kind kConstructor, which indicates either a generative constructor or a factory constructor.

vegorov@google.com e31313efea Refactor _ByteDataView.[set|get]<Type> methods to improve their performance. 
- don't manually truncate values before passing them to TypedData._[set|get]<Type> - these methods already have truncating semantics;

- don't call into runtime for endianess conversion, implement it in pure Dart instead (with an intent to provide optimized version on platforms that support fast byte-swapping instructions);

- force inlining of these methods (change the order of checks in the ShouldWeInline to guarantee inlining of whitelisted methods).

Unrelated change:

- tweak output of Function::CheckSourceFingerprint to be immediately copy&paste useful.

An invisible function is hidden from stack traces, will not be enumerated
by mirrors, and cannot be directly invoked by mirrors. Note that private
classes remain accessible.

Fix a few internal dart:io functions that should be private.

Fix bug where mirrors would enumerate top-level invisible functions.

mirrors as failing.

koda@google.com 0b85873fc8 Deletion barrier preparation: validate overwritten references. 
With the upcoming deletion barrier, every update of a pointer field must know whether the previous value was a valid pointer.

Currently, we always use StorePointer/StoreSmi, both for initialization and updates.

Initialization, and thus the potential for overwriting garbage values, appears in three places:
1. Object::Allocate/Foo::New.
2. Creating isolate from full snapshot.
3. Allocation in generated code.

Case 1 already null-initializes all underlying memory.
Case 2 is addressed by this CL by exploiting that:
i) fresh pages are zero-filled by OS, and
ii) freelist headers use only even values.
Case 3 is remains a TODO for future CLs.

(An alternative solution for case 2 would have been to add an init_foo method for every set_foo called.)
