commit 14577312211e25024ffd90bbded44b021877fc59
Author: Andy Polyakov <[email protected]>

poly1305/asm/poly1305-armv4.pl: replace ambiguous instruction.
Different assembler versions disagree on how to interpret #-1 as
argument to vmov.i64, as 0xffffffffffffffff or 0x00000000ffffffff.
So replace it with something they can't disagree on.
