AArch64: Add LUTI ACLE for SVE2
This patch introduces support for LUTI2/LUTI4 ACLE for SVE2.
LUTI instructions are used for efficient table lookups with 2-bit
or 4-bit indices. LUTI2 reads indexed 8-bit or 16-bit elements from
the low 128 bits of the table vector using packed 2-bit indices,
while LUTI4 can read from the low 128 or 256 bits of the table
vector or from two table vectors using packed 4-bit indices.
These instructions fill the destination vector by copying elements
indexed by segments of the source vector, selected by the vector
segment index.
The changes include the addition of a new AArch64 option
extension "lut", __ARM_FEATURE_LUT preprocessor macro, definitions
for the new LUTI instruction shapes, and implementations of the
svluti2 and svluti4 builtins.
