Dmitry Vyukov 0781895e0f pkg/compiler: refactor attribute handling
Introduce common infrastructure for describing and parsing attribute
instead of custom per-attribute code scattered across several locations.

Change align attribute syntax from the weird align_N to align[N].
This also allows to use literal constants as N.

Introduce notion of builtin constants.
Currently we have only PTR_SIZE, which is needed to replace
align_ptr with align[PTR_SIZE].
