This removes the UC_ASSERT_ERR_ANY constant, which was causing a
compilation error on OSX:
error: comparison of constant 3735928559 with expression of type
'uc_err' (aka 'enum uc_err') is always true
[-Werror,-Wtautological-constant-out-of-range-compare]
I could have probably changed 0xDEADBEEF to a constant < 0x80000000
but this seems cleaner anyway.
