The data layout strings do not have any effect on llc tests and will become misleadingly out of date as we continue to update the canonical data layout, so remove them from the tests. Differential Revision: https://reviews.llvm.org/D105842

# In the two tests below, without compiler_fence or atomic.fence in between,
|
|
# memory.atomic.notify and i32.add will be reordered by register stackify pass
|
|
# to meet 'call @foo''s requirements. But because we have fences between
|
|
# memory.atomic.notify and i32.add, they cannot be reordered, and local.set and
|
|
# local.get are inserted to save and load memory.atomic.notify's return value.
