[InstCombine][SVE] Fix visitGetElementPtrInst for scalable type.
Summary:
This patch fix the following issues in InstCombiner::visitGetElementPtrInst
1. Skip for scalable type if transformation requires fixed size number of
vector element.
2. Skip for scalable type if transformation relies on compile-time known type
alloc size.
3. Use VectorType::getElementCount when scalable property is used to construct
new VectorType.
4. Use TypeSize::getKnownMinSize when minimal size of a scalable type is valid to determine GEP 'inbounds'.
5. Explicitly call TypeSize::getFixedSize to avoid implicit type conversion to uint64_t.
