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 makes sure that the {WasmGraphBuilder} properly detects the
presence of Simd128 loads and store opcodes and triggers then scalar
lowering of the graph on architectures that don't support Simd128.

This brings our constants back in line with the changed spec text. We
already use kExprTableGet and kExprTableSet, but for locals and globals
we still use the old wording.
This renaming is mostly mechanical.
PS1 was created using:
ag -l 'kExpr(Get|Set|Tee)Local' src test | \
xargs -L1 sed -E 's/kExpr(Get|Set|Tee)Local\b/kExprLocal\1/g' -i
PS2 contains manual fixes.

This switches the experimental exception handling implementation to the
new proposal where 'catch' blocks behave in a catch-all fashion and a
new 'br_on_exn' operation is used to check for a certain exception type
and extract the exception values on a match.
