x86: break mutual header inclusion

Browse source 
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'.
