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.

- Update opcode numbers, tests
- As the wasm-module-builder currently assumes opcode bytes, skip
the test that needs a multi-byte leb128 opcode
- Renumber post-MVP opcodes

This is a reland of 548fda4afb
regress-1054466 is modified to not use 64x2 operations, since that was
causing problems on noavx/nosse builds, which requires scalar lowering,
and scalar lowering for 64x2 ops is not implemented.

Given two registers that are both not gp_pair, one could be an fp_pair,
and the other not, and we will incorrect call == on them. The current
check needs to be expanded to check that both registers are fp_pair.
