target/arm: Fix calculation of LTP mask when LR is 0
In mve_element_mask(), we calculate a mask for tail predication which
should have a number of 1 bits based on the value of LR. However,
our MAKE_64BIT_MASK() macro has undefined behaviour when passed a
zero length. Special case this to give the all-zeroes mask we
require.
