  Log Message:
  -----------
  [WebAssembly] Add end-to-end codegen tests for wasm_simd128.h

Add a test checking that each SIMD intrinsic produces the expected instruction.
Since this test spans both clang and LLVM, place it in a new
intrinsic-header-tests subdirectory of cross-project-tests.

This revives D101684 now that cross-project-tests exists. In practice, the tests
of lowering from wasm_simd128.h to LLVM IR were not as useful as this end-to-end
test.

Updates the version check of gdb in cross-project-tests/lit.cfg.py so that
unexpected version formats do not prevent the new tests from running.

Depends on D121661.
