re PR sanitizer/60038 (AddressSanitizer CHECK failed ... "((*tls_addr + *tls_size)) <= ((*stk_addr + *stk_size))" on CentOS 5.10)

	PR sanitizer/60038
	* sanitizer_common/sanitizer_linux_libcdep.cc: Include
	sanitizer_atomic.h and unistd.h.
	(kThreadDescriptorSize): Made static, remove initializer and const,
	change type to atomic_uintptr_t.
	(ThreadDescriptorSize): Use confstr(_CS_GNU_LIBC_VERSION, ...) to
	query glibc version, compute kThreadDescriptorSize depending on
	glibc version minor number.
	(GetThreadStackAndTls): Use ThreadDescriptorSize() instead of
	kThreadDescriptorSize directly.
