Hojun-Cho 1657bdeda3 ww: import toolchain — C bootstrap + ww-side self-host (phases 0-10)
C bootstrap (phases 0-9):
  cmd/wwc, cmd/6c, cmd/6a, cmd/6l, cmd/ww, rt, lib/*.

ww-side self-host (phase 10):
  selfhost/cmd/wwc — ww-cgen frontend; bootstrap fixed point.
  selfhost/cmd/6a  — assembler; byte-identical to C 6a (test 991).
  selfhost/cmd/6l  — linker w/ archive (.a) support; byte-identical
                     to C 6l (test 992).
  selfhost/cmd/ww  — driver (build/run/version); byte-identical to
                     C ww (test 993).

make test: 15/15. make bootstrap: ww2.s == ww3.s, ww2.o == ww3.o,
ww2 == ww3 byte-identical, with the full ww-tooled chain.

// No closures, no methods. A `stream` is a struct of function
// pointers plus a `ctx: *void`. The error channel is the return
// value of read/write/close. Negative i32 = errno-style code,
// non-negative = bytes transferred.
