Handle CPU interrupts by inline checking of a flag
Fix some of the nasty TCG race conditions and crashes by implementing
cpu_exit() as setting a flag which is checked at the start of each TB.
This avoids crashes if a thread or signal handler calls cpu_exit()
while the execution thread is itself modifying the TB graph.
This commit reflects following two commits from QEMU ToT:
Main part of the solution:
378df4b Handle CPU interrupts by inline checking of a flag
Code cleanup:
3a808cc translate-all.c: Remove cpu_unlink_tb()
