x86: break mutual header inclusion
This breaks up the mutual inclusion between headers ptrace.h and vm86.h by moving some small part of vm86.h which is needed by ptrace.h into processor-flags.h. We also try to move #include lines to the top. This has been compile tested on x86_32 and x86_64 defconfig, and run through 'make headers_check'.
