Commit Message

Replace x86 setz instruction by asm flag output operand (gcc)

If the compiler support flag outputs, then we can get rid of setz
instruction.

* src/atomic_ops/sysdeps/gcc/x86.h [AO_DISABLE_GCC_ATOMICS
&& !AO_GENERALIZE_ASM_BOOL_CAS && !AO_USE_SYNC_CAS_BUILTIN]
(AO_compare_and_swap_full): If __GCC_ASM_FLAG_OUTPUTS__ is defined,
then define dummy local variable and store cmpxchg result to it, fill
in "result" varaible using @ccz asm specification, do not use asm setz
instruction.
* src/atomic_ops/sysdeps/gcc/x86.h [AO_GCC_ATOMIC_TEST_AND_SET
&& !AO_SKIPATOMIC_double_compare_and_swap_ANY]
(AO_compare_double_and_swap_double_full):  If __GCC_ASM_FLAG_OUTPUTS__
is defined, then do not define dummy local variable, fill in "result"
variable using @ccz asm specification, do not use asm setz instruction,
specify that old_val2 and old_val1 are modified by cmpxchg8/16b
instruction.
