Paolo Bonzini 35d95e4126 target/i386: hardcode R_EAX as destination register for LAHF/SAHF
When translating code that is using LAHF and SAHF in combination with the
REX prefix, the instructions should not use any other register than AH;
however, QEMU selects SPL (SP being register 4, just like AH) if the
REX prefix is present.  To fix this, use deposit directly without
going through gen_op_mov_v_reg and gen_op_mov_reg_v.
