After introduction of lock_evaluate_nospec() using bool type, building
Xen on Arm with UBSAN enabled fails:
In file included from ./include/xen/spinlock.h:4,
from common/ubsan/ubsan.c:13:
./include/xen/nospec.h:79:22: error: unknown type name ‘bool’
79 | static always_inline bool lock_evaluate_nospec(bool condition)
There is no issue on x86, as xen/stdbool.h is included somewhere along
the asm/nospec.h path, which is not the case for other architectures.
Fixes: 7ef0084418e1 ("x86/spinlock: introduce support for blocking speculation
into critical regions")
