Test was skipped because the generated test contains multi-byte opcode,
and wasn't correct. Fix up the test with the correct encoding. The
fuzzer now generates multi-byte opcodes correctly, and so shouldn't be
an issue.

The proposal uses the lane shape, e.g. i64x2.anytrue, and we were using
s1x2.anytrue in our opcodes. This was a legacy naming, because we were
trying to bitpack the booleans. Now that we aren't doing that, rename
these to be more consistent with the proposal.
This was done with a straightforward sed script, changing both cpp code
and also some comments in mjsunit test files.

This relands commit 7d955faa76.
Changed the test case to use i16x8 splat instead of i8x16 splat,
the latter was causing issues when doing scalar lowering. This
change still causes the regression test to fail without the fix.
