7bb6791af9 AddPadding: Insert padding at the beginning of structs if necessary
This is sometimes needed now that we're removing members before adding
padding.

8b7bfbe4c0 TypeGraph: Add EnforceCompatibility pass
This extracts the compatibility logic from AddPadding, which allows for it to be
simplified and will make it easier to extend and eventually remove in the
future. No functional changes.

04ce7446b2 AddPadding: Always pad bitfields with "int8_t"s
The underlying type of bitfield is important to the size of a struct:

  struct Foo { int64_t bitfield : 1; };
  struct Bar { int8_t bitfield : 1; };

  sizeof(Foo) = 8;
  sizeof(Bar) = 1;

3ec81aaa5f TypeGraph: Add "--tree-builder-v2" flag
This will eventually be used to enable running with Tree Builder v2.

For now, when it is disabled it puts CodeGen v2 into compatibility mode,
disabling features which weren't present in CodeGen v1 so that its
output can be understood by Tree Builder v1.

e1b16a3d7e TypeGraph: Switch from pointers to references
References must always have a value, so are semantically clearer than
pointers for variables which must always be set.

No functional changes.

23efc8d2d6 TypeGraph: Add Node IDs to non-leaf types
These aren't used for anything yet, but should be useful for stable IDs
when printing nodes before and after passes and for faster cycle
detection than the current map of pointers.

e86ebb7aff TypeGraph: Support bitfields
- Change member and parent offsets to work in bits, not bytes
- Printer still displays offsets in bytes, with decimals when using
  bitfields
- AddPadding: Don't pad bitfields
- CodeGen: Emit code for bitfields

00b46377a1 Unit tests: Remove unnecessary make_unique calls
This was a purely mechanical change made with some find-and-replace
macros.

bd919ae4e4 TypeGraph: Add core code
This code mostly works, but is obviously not complete. This commit just
adds the code and tests, but does not enable it in OID or OIL.
