tcg: Use bitmaps for free temporaries

We previously allocated 32-bits per temp for the next_free_temp entry.
We now allocate 4 bits per temp across the 4 bitmaps.

Using a linked list meant that if a translator is tweeked, resulting in
temps being freed in a different order, that would have follow-on effects...

tcg-s390: Use qemu_getauxval in query_facilities

No need to set up a SIGILL signal handler for detection anymore.

Remove a ton of sanity checks that must be true, given that we're
requiring a 64-bit build (the note about 31-bit KVM is satisfied
by configuring with TCI)....

tcg-ia64: Introduce tcg_opc_ext_i

Being able to "extend" from 64-bits (with a mov) simplifies
a few places where the conditional breaks the train of thought.

tcg-ia64: Use SUB_A3 and ADDS_A4 for subtraction

We can subtract from more small constants that just 0 with one insn,
and we can add the negative for most small constants.
