    xen/compiler: Fix the position of the visibility pragma
    
    This needs to be ahead of everything.  Right now, it is after xen/init.h 
being
    included for -DINIT_SECTIONS_ONLY
    
      # 1 "./include/xen/compiler.h" 1
      # 83 "./include/xen/compiler.h"
      # 1 "./include/xen/init.h" 1
      # 62 "./include/xen/init.h"
      typedef int (*initcall_t)(void);
      typedef void (*exitcall_t)(void);
      # 72 "./include/xen/init.h"
      void do_presmp_initcalls(void);
      void do_initcalls(void);
      # 84 "./include/xen/compiler.h" 2
      # 122 "./include/xen/compiler.h"
      #pragma GCC visibility push(hidden)
    
    Fixes: 84c4461b7d3a ("Force out-of-line instances of inline functions into 
.init.text in init-only code")
