282ef7e8ef tcg/ppc: Add TCG_CT_CONST_CMP
Better constraint for tcg_out_cmp, based on the comparison.
We can't yet remove the fallback to load constants into a
scratch because of tcg_out_cmp2, but that path should not
be as frequent.

526cd4ec01 tcg/ppc: Support 128-bit load/store
Use LQ/STQ with ISA v2.07, and 16-byte atomicity is required.
Note that these instructions do not require 16-byte alignment.

b41b43a477 tcg/ppc: Adjust constraints on qemu_ld/st
The softmmu tlb uses TCG_REG_{TMP1,TMP2,R0}, not any of the normally
available registers.  Now that we handle overlap betwen inputs and
helper arguments, we can allow any allocatable reg.
