target/i386: adapt gen_shift_count for SHLD/SHRD

SHLD/SHRD can have 3 register operands - s->T0, s->T1 and either
1 or CL - and therefore decode->op[2] is taken by the low part
of the register being shifted.  Pass X86_OP_* to gen_shift_count
from its current callers and hardcode cpu_regs[R_ECX] as the
shift count.
