Fix IFN_MASK_STORE handling of IFN_GOMP_SIMD_LANE
The IFN_GOMP_SIMD_LANE handling in vectorizable_store tries to use MEM_REF
offsets to maintain pointer disambiguation info. This patch makes sure
that we don't try to do the same optimisation for IFN_MASK_STOREs, which
have no similar offset argument.
The patch fixes libgomp.c-c++-common/pr66199-*.c for SVE. Previously
we had an ncopies==2 store and stored both halves to the same address.

* tree-vect-stmts.c (vectorizable_store): Don't use the dataref_offset
optimization for masked stores.
