`--bits 32` generates i386 code: eight registers (ebp holds the blob; esi and
edi stay free for the string forms), widths without 64, ah/ch/dh/bh where
64-bit code has spl..dil, a harness that enters through `int 0x80`, and
`as --32`/`ld -m elf_i386`. The host runs the i386 binary itself, so the
CPU is still the oracle; gexc runs it in compatibility mode. 297 of 300
cases assemble and 296 agree; the one that does not is a shared SSE bug
(packed cvttps2dq saturates where the CPU returns the integer indefinite).
