This adds WebAssembly support for the new [Lime1 CPU].
First, this defines some new target features. These are subsets of
existing
features that reflect implementation concerns:
- "call-indirect-overlong" - implied by "reference-types"; just the
overlong
encoding for the `call_indirect` immediate, and not the actual reference
types.
- "bulk-memory-opt" - implied by "bulk-memory": just `memory.copy` and
`memory.fill`, and not the other instructions in the bulk-memory
proposal.
Next, this defines a new target CPU, "lime1", which enables
mutable-globals,
bulk-memory-opt, multivalue, sign-ext, nontrapping-fptoint,
extended-const,
and call-indirect-overlong. Unlike the default "generic" CPU, "lime1" is
meant
to be frozen, and followed up by "lime2" and so on when new features are
desired.
