[RISCV] Update matchSplatAsGather to use the index of extract_elt if in-bounds (#118873)
This is a follow-up to #117878 and allows the usage of vrgather if the index
we are accessing in VT is constant and within bounds.
This patch replaces the previous behavior of bailing out if the length of the
search vector is greater than the vector of elements we are searching for.
Since matchSplatAsGather works on EXTRACT_VECTOR_ELT, and we know the index
from which the element is extracted, we only need to check if we are doing an
insert from a larger vector into a smaller one, in which we do an extract
instead.
