RISC-V: Add vec_init expander for masks [PR112854].
PR112854 shows a problem on rv32 with zvl1024b. During the course of
expand_constructor we try to overlay/subreg a 64-element mask by a
scalar (Pmode) register. This works for zvl512b and its maximum of
32 elements but fails for rv32 and 64 elements.
To circumvent this this patch adds a vec_init expander for vector masks
by initializing a QImode vector and comparing that against 0.
