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.

Use LQ/STQ with ISA v2.07, and 16-byte atomicity is required.
Note that these instructions do not require 16-byte alignment.

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.
