x86 cleanup
Remove some unnecessary includes, add needed includes, move prototypes to cpu.h to suppress missing prototype warnings. Remove unused functions and prototypes (cpu_x86_flush_tlb, cpu_lock, cpu_unlock, restore_native_fp_state, save_native_fp_state). Make some functions and data static (f15rk, parity_table, rclw_table, rclb_table, raise_interrupt, fpu_raise_exception), they are not used outside op_helper.c anymore. Make some x86_64 and user only code conditional to avoid warnings. Document where each function is implemented in cpu.h and exec.h. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6005 c046a42c-6fe2-441c-8c8c-71466251a162
