[012568kqv]a: correctly lex full range of integers in the assemblers (thanks Ori_B) The Plan 9 assemblers use strtoll to parse the integer literals in their input. It turns out that this is almost correct, but VLONG_MIN is clamped. This patch changes to use strtoull in order to allow the full range of integers.
