tcg/tci: Fix TCG_REG_R4 misusage
This was removed from tcg_target_reg_alloc_order and
tcg_target_call_iarg_regs on the assumption that it
was the stack. This was incorrectly copied from i386.
For tci, the stack is R15.
By adding R4 back to tcg_target_call_iarg_regs, adjust the other
entries so that 6 (or 12) entries are still present in the array,
and adjust the numbers in the interpreter.
