Several WebAssembly tests fail on LLVM without X86 target

[aaronpuchert]

I get these failures when running LLVM tests without X86 target:

Failed Tests (5):

Is it intentional that WebAssembly tests use X86 object files? If yes, we should probably add REQUIRES: x86-registered-target.

@CarlosAlbertoEnciso as the test cases seem to come from b19cfb9.

@aaronpuchert The .s files used as input for the WebAssembly tests were generated on a system with LLVM default target triple: x86_64-pc-linux-gnu.
You are correct. We should add REQUIRES: x86-registered-target.
There are already some tests in llvm/test/tools/llvm-debuginfo-analyzer/DWARF that use REQUIRES: x86-registered-target.

[ppenzin]

Why should wasm debuginfo tests require x86 target? The assembly files seem to be all wasm, or should they not be all wasm?
