The goal here is to reduce the amount of code generation when the
guest kernel enables address space randomization. This requires
extensive changes to each target, so opt-in with TARGET_TB_PCREL.
This is split out of v3, which also contained target/arm changes,
as I now have patches for x86 and s390x as well.
