There are now quite a few SVE tests in LLVM and Clang that do not
emit warnings related to invalid use of EVT::getVectorNumElements()
and VectorType::getNumElements(). For these tests I have added
additional checks that there are no warnings in order to prevent
any future regressions.

The ACLE distinguishes between the following addressing modes for gather
loads:
* "scalar base, vector offset", and
* "vector base, scalar offset".
For the "vector base, scalar offset" case, the
`int_aarch64_sve_ld1_gather_imm` intrinsic was added in 79f2422d.
Currently, that intrinsic assumes that the scalar offset is passed as an
immediate. As a result, it does not cater for cases where scalar offset
is stored in a register.
In this patch `int_aarch64_sve_ld1_gather_imm` is extended so that all
cases are covered:
* `int_aarch64_sve_ld1_gather_imm` is renamed as
`int_aarch64_sve_ld1_gather_scalar_offset`
* new DAG combine rules are added for GLD1_IMM for scenarios where the
offset is a non-immediate scalar or an out-of-range immediate
* sve-intrinsics-gather-loads-vector-base.ll is renamed as
sve-intrinsics-gather-loads-vector-base-imm-offset.ll
* sve-intrinsics-gather-loads-vector-base-scalar-offset.ll is added to test
file for non-immediate offsets
Similar changes are made for scatter store intrinsics.
