We want to be consistent with wasdk/wasmparser.

The names used in V8 should follow the WAT convention and always start
with a dollar, both for names from the "names" section as well as
generated names.

By replacing usage of the IsNotArrayIndex bit with IsNotIntegerIndex,
we get back one bit that we can use to increase the number of hash bits
stored. The price is that strings that represent array/integer indices
beyond the cacheable range will have to be scanned more often, but these
strings should be rare, and we expect that the additional hash bit is
more worthwhile to have.

Currently, when debugging wasm, the internal script URL is shown, which
has the form wasm://wasm/wasm-<hex-script-id>. With this change, if the
module specifies a module name, it would report the URL as
wasm://wasm/<module-name>-<hex-script-id>, as this will help the user
identify what they are debugging.

This is useful for the upcoming "huge TypedArrays" support, to be able
to quickly decide in stubs/generated code whether a string used as the
key for a property load/store can possibly be an exotic integer index.

If script is not disassembled, still use the same script URL format for
consistency.

In particular, use an absolute `wasm://wasm/` prefix, like disassembled fake
scripts do, instead of just a script name which appears to be a
relative URL to devtools.

For wasm modules with non-absolute sourceMappingURL, the source needs
to be empty so that devtools can look for the source map at the origin
of the module.

This CL enables source maps support for wasm. Devtools should
be able to pick up source_mapping_url parsed here and load the
corresponding source maps.
