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 where the element is being extracted from, we can safely use vrgather.

Subject: [PATCH] [RISCV] Update matchSplatAsGather to use the index of
extract_elt if it is in-bounds
This a follow up to #117878 and allows the usage of vrgather if the
index we are accessing in VT is a constant and within bounds.
This patch replaces the previous behavior of bailing out if the length
of the search vector was greater than the vector of elements we are
searching for. Since matchSplatAsGather works on EXTRACT_VECTOR_ELT, and
we know the index where the element is being extracted from, we can use
safely use vrgather.
