[Qemu-devel] [PULL 07/19] cpu-defs: Move out TB_JMP defines

[Paolo Bonzini]

From: Peter Crosthwaite <address@hidden>

These are not Architecture specific in any way so move them out of
cpu-defs.h. tb-hash.h is an appropriate place as a leading user and
their strong relationship to TB hashing and caching.
