translate-all: Move tcg_handle_interrupt() to -common

Browse source 
Move this function to common code. It has no arch specific
dependencies. Prepares support for multi-arch where the translate-all
interface needs to be virtualised. One less thing to virtualise.

Backports commit 9b68a7754a892d8deb7696cfe609fe2ec3c6034a from qemu
