wasm simd 128 build failure regression

[xloem]

I’m trying out building on a-shell on iOS which is a wasm terminal platform without gnu make.

It looks like since c1f8850 there are undefined symbols in the wasm simd 128 code:

clang -pipe  -msimd128 -D_WASI_EMULATED_MMAN -D_WASI_EMULATED_PROCESS_CLOCKS   -c ggml.c -o ggml.o
ggml.c:2090:43: error: use of undeclared identifier 'px'
        const block_q4_0 * restrict x0 = &px[i + 0];
                                          ^

These undefined symbols were first introduced on line 1726 of ggml.c c1f8850#diff-6d9ce99fcb6f51ff76f59e479f6e6fc0bb62edef7442805d7a5bb15b23996b5dR1726 (github seems to need the large diff manually expanded) and is presently at https://github.com/ggerganov/llama.cpp/blob/d2beca95dcfcd6f1145886e914b879ffc3604b7a/ggml.c#L2090

@xloem : I apologize, I broke this without ever testing it in wasm. Unfortunately I can't seem to get the toolchain right here, because I'm still getting errors about wasm_u8x16_splat which I didn't touch in #356. Can you check if sw@d1315a3 works for you?

This error is resolved in the referenced commit. (I still haven’t performed a full build on this platform yet, it lacks gnu make and has a version of llvm from before there was full wasm pthread support)
