Changelog v1->v2:
- Dropped push sreg part.
- Covered CMPS and SCAS
- Removed useless emulate_* functions
- Replaced D6ALU macro with I6ALU
- Various rebases.
I also updated the titles and changelogs to be consistent with
Avi's recent patches.

From: Takuya Yoshikawa <yoshikawa.takuya@oss.ntt.co.jp>
The following instructions are changed to use opcode::execute.
Group 1 (80-83)
ADD (00-05), OR (08-0D), ADC (10-15), SBB (18-1D), AND (20-25),
SUB (28-2D), XOR (30-35), CMP (38-3D)
CMPS (A6-A7), SCAS (AE-AF)
The last two do the same as CMP in the emulator, so em_cmp() is used.
