x86: drop dqa_mode

Browse Source 
I assume this mode was needed when EVEX.W handling wasn't really correct
yet for other than 64-bit mode. It's clearly not needed anymore. Its
elimination also allows dropping the EVEX.W split of VCVT{,U}SI2SS. (For
the record, the dropped mode would have been wrong if used in any table
entry not already guaranteeing EVEX.W=1.)

* i386-dis.c (Edqa, dqa_mode, EVEX_W_0F2A_P_1, EVEX_W_0F7B_P_1):
Delete.
(intel_operand_size, OP_E_register, OP_E_memory): Drop handling
of dqa_mode.
* i386-dis-evex-prefix.h: Move vcvtsi2ss and vcvtusi2ss leaf
entries here.
* i386-dis-evex-w.h: Drop EVEX_W_0F2A_P_1 and EVEX_W_0F7B_P_1
entries. Use Edq for vcvtsi2sd and vcvtusi2sd.

* i386-dis.c (OP_I64): Forword more cases to OP_I(). Drop local
