Since the reftypes proposal has shipped, we remove the respective flag
and the code that handled its absence. We maintain a WasmFeature for
reftypes for feature detection purposes. We remove the flag declaration
from tests, and adapt some tests that make no sense without the flag.

The default value for table entries in WebAssembly tables is null when
the table gets allocated from WebAssembly, but when the table gets
allocated from JavaScript, the default value is undefined when the
table type is externref. With this CL V8 handles the JavaScript case
spec-compliant.

This was not happening when there was no need to typecheck the entry.
Additional changes:
- Add tests with null table entries for typed and untyped function
tables.
- Allow AddIndirectFunctionTable in wasm-run-utils to specify table
type.
- Add possibility to define tables in test-gc.cc.
- Merge trapTableOutOfBounds with trapInvalidFunc.
- Use trapTableOutOfBounds in call_indirect as appropriate.
- Fix emission of table types in wasm-module-builder.cc.

The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.

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.

When I implemented these instructions, I copied the naming scheme of
{GetGlobal}. That's not appropriate for the table.get instruction
though, and I decided I suffered enough from that bad name now.

This CL add decoding and code generation for the table.grow
instruction. For code generation we just generate a runtime
call. The implementation is quite straight-forward. However,
I did several small cleanups along the way. I hope it's still
acceptable. I could also split out some cleanups into separate
CLs.
