tcg: Reload local variables after return from longjmp
Recent compilers look deep into cpu_exec, find longjmp as a noreturn function and decide to smash some stack variables as they won't be used again. This may lead to env becoming invalid after return from setjmp, causing crashes. Fix it by reloading env from cpu_single_env in that case.
