selfhost/cmd/{w6a,w6l}: migrate 10 amalloc sites to alloc(T{...})!

Browse Source 
Phase 0 batch 2. Sites: w6a/parse.ww (asym, aprog, aoperand ×2),
w6l/main.ww (lnk), w6l/obj.ww (defent, armember, lobj, lrel ×2).

obj.ww's hdrsize *u8 buffer at line 344 + 7 other runtime-N byte
buffers across the three files (path bufs, n+1 cstr copies, cap
realloc) stay deferred to #8.

Verified via 991_w6a_ww + 992_w6l_ww + 995_self_rebuild +
996_dyn_ww byte-identity. make test 132/132.
