Many hosts pass and return 128-bit quantities like sequential

Begin staging in support for TCGv_i128 with Int128.
Define the type enumerator, the typedef, and the
helper-head.h macros.

This cannot yet be used, because you can't allocate
temporaries of this new type.

After commit 4e4fa6c1 ("accel/tcg: Complete cpu initialization
before registration"), it looks the CPUJumpCache pointer can be NULL.
This causes a SIGSEV when running debug-wp-migration kvm unit test.

At the first place it should be clarified why this TCG code is called
with KVM acceleration. This may hide another bug.
