varasm: Fix ICE with -fsyntax-only [PR99035]
My FE change from 2 years ago uses TREE_ASM_WRITTEN in -fsyntax-only
mode more aggressively to avoid "expanding" functions multiple times.
With -fsyntax-only nothing is really expanded, so I think it is acceptable
to adjust the assert and allow declare_weak at any time, with -fsyntax-only
we know it is during parsing only anyway.

TREE_ASM_WRITTEN function decls.
