Thomas Lively 81bb5f99ad [WebAssembly] Remove datalayout strings from llc tests
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misleadingly out of date as we continue to update the canonical data layout, so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.

; The following tests check that frame index elimination works for
; bulk memory instructions. The stack pointer is bumped by 112 instead
; of 100 because the stack pointer in WebAssembly is currently always
; 16-byte aligned, even in leaf functions, although it is not written
; back to the global in this case.
; TODO: Change TransientStackAlignment to 1 to avoid this extra
; arithmetic. This will require forcing the use of StackAlignment in
; PrologEpilogEmitter.cpp when
; WebAssemblyFrameLowering::needsSPWriteback would be true.
