tcg/mips: Fix type of tcg_target_reg_alloc_order[]

The MIPS TCG backend is the only one to have
tcg_target_reg_alloc_order[] elements of type TCGReg rather than int.
This resulted in commit 91478cefaaf2 ("tcg: Allocate indirect_base
temporaries in a different order") breaking the build on MIPS since the
type differed from indirect_reg_alloc_order[]:

tcg/tcg.c:1725:44: error: pointer type mismatch in conditional expression [-Werror]
     order = rev ? indirect_reg_alloc_order : tcg_target_reg_alloc_order;
                                            ^

Make it an array of ints to fix the build and match other architectures.

Sorry, I've had the same fix queued for some time, but have
failed to include it in a tcg pull.  I'll rectify that soon.

Richard, do you have a pending TCG pull request in which you can include
this one?
