This patch removes the intrinsic aarch64.sve.ldN from tablegen in favour of
using arch64.sve.ldN.sret.

The old intrinsic is still supported, but there is a regression.
This is because we do not apply a combine in the AutoUpgrade  that used to
exist in LowerSVEStructLoad function.

Previously the aarch64.sve.ldN used LowerSVEStructLoad function to concatenate
the results from LD. This patch removes this function because the intrinsic
aarch64_sve_ld2 does not exist when lowering.
