tcg: Add qemu_ld_st_i32/64

Step two in the transition, adding the new ldst opcodes. Keep the old

tcg-ppc64: Fold constant call address into descriptor load

Eliminates one insn per call:

:  lis     r2,4165
:  ori     r2,r2,59616
:  ld      r0,0(r2)
:  ld      r0,-5920(r2)
 :  mtctr   r0
-:  ld      r2,8(r2)
:  ld      r2,-5912(r2)
 :  bctrl

tcg-ppc64: Look through a constant function descriptor

Especially in the user-only configurations, a direct branch into

tcg-ppc64: Tidy register allocation order

Remove conditionalization from tcg_target_reg_alloc_order, relying on
reserved_regs to prevent register allocation that shouldn't happen.
So R11 is now present in reg_alloc_order for APPLE, but also now

tcg-ppc64: Handle long offsets better

Previously we'd only handle 16-bit offsets from memory operand without falling
back to indexed, but it's easy to use ADDIS to handle full 32-bit offsets.

This also lets us unify code that existed inline in tcg_out_op for handling...

tcg-ppc64: Streamline tcg_out_tlb_read

Less conditional compilation. Merge an add insn with the indexed
memory load insn. Load the tlb addend earlier. Avoid the address
update memory form.

Fix a bug in not allowing large enough tlb offsets for some guests....

tcg-ppc64: Add _noaddr functions for emitting forward branches

... rather than open-coding this stuff through the file.
