Heiko Carstens 6166caf3bb s390/bitops: Disable arch_test_bit() optimization for PROFILE_ALL_BRANCHES 
With PROFILE_ALL_BRANCHES enabled gcc sometimes fails to handle
__builtin_constant_p() correctly:

   In function 'arch_test_bit',
       inlined from 'node_state' at include/linux/nodemask.h:423:9,
       inlined from 'warn_if_node_offline' at include/linux/gfp.h:252:2,
       inlined from '__alloc_pages_node_noprof' at include/linux/gfp.h:267:2,
       inlined from 'alloc_pages_node_noprof' at include/linux/gfp.h:296:9,
       inlined from 'vm_area_alloc_pages.constprop' at mm/vmalloc.c:3591:11:
>> arch/s390/include/asm/bitops.h:60:17: warning: 'asm' operand 2 probably does not match constraints
      60 |                 asm volatile(
         |                 ^~~
>> arch/s390/include/asm/bitops.h:60:17: error: impossible constraint in 'asm'

Therefore disable the optimization for this case. This is similar to
commit 63678eecec ("s390/preempt: disable __preempt_count_add()
optimization for PROFILE_ALL_BRANCHES")

Fixes: b2bc1b1a77 ("s390/bitops: Provide optimized arch_test_bit()")
