Section handling: finer control of variable initialization
Distinguish between:
- uninitialized variables, which can go in COMM if supported
- variables initialized with fixed, numeric quantities,
which can go in a readonly section if "const"
- variables initialized with symbol addresses which may need relocation,
which cannot go in a readonly section even if "const",
but can go in a special "const_data" section.
Also: on macOS, use ".const" instead of ".literal8" for literals,
as not all literals have size 8.
