X86 entry code related updates:

 - Consolidate the macros for .byte ... opcode sequences

 - Deduplicate register offset defines in include files

 - Simplify the ia32,x32 compat handling of the related syscall tables to
   get rid of #ifdeffery.

 - Clear all EFLAGS which are not required for syscall handling

 - Consolidate the syscall tables and switch the generation over to the
   generic shell script and remove the CFLAGS tweaks which are not longer
   required.

 - Use 'int' type for system call numbers to match the generic code.

 - Add more selftests for syscalls
x86/syscalls: Don't adjust CFLAGS for syscall tables

The syscall_*.c files only contain data (the syscall tables).  There
is no need to adjust CFLAGS for tracing and stack protector since they
contain no code.
