Thomas Lively 122b0220fd [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misleadingly out of date as we continue to update the canonical data layout, so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.

; Regression test for a crash caused by
; WebAssemblyTargetLowering::ReplaceNodeResults not being
; implemented. Since SIMD is enabled, sign_ext_inreg is custom lowered
; but the result is i16, an illegal value. This requires
; ReplaceNodeResults to resolve, but the default implementation is to
; abort.
