target/mips: Use tcg_constant_tl() instead of tcg_gen_movi_tl()

Directly use tcg_constant_tl() for constant integer, this
save a call to tcg_gen_movi_tl(), often saving a temp register.

Most of the places found using the following Coccinelle spatch script:

  @@
  identifier tmp;
  constant val;
  @@
  *    TCGv tmp = tcg_temp_new();
       ...
  *    tcg_gen_movi_tl(tmp, val);

  @@
  identifier tmp;
  int val;
  @@
  *    TCGv tmp = tcg_temp_new();
       ...
  *    tcg_gen_movi_i64(tmp, val);
