Element segments and tables in tests used an ad-hoc mechanism to
describe the different types of initializer expressions, e.g. an number
which could denote either the value of a constant or the index of a
global. This CL tidies up and generalizes the test infrastructure by
directly using WasmInitExpr in those cases.
Additional changes:
- Introduce WasmElemSegment class.
- Remove obsolete --experimental-wasm-bulk-memory flag from tests.
- Rename WasmInitExpr.type -> kind.
- Remove dependency of wasm-module-builder from mjsunit.js (except in
assertTraps).

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)Global' src test | \
xargs -L1 sed -E 's/kExpr(Get|Set)Global\b/kExprGlobal\1/g' -i
PS2 contains manual fixes.

Most of the mjsunit/wasm/table-copy.js tests have been ported to
cctests, so they can be tested with all execution tiers.

This CL just adds a parameter to addElementSegment and adjusts all
existing tests.
Note that addElementSegment contains some convenience code to construct
one initial table if it does not exist yet. I did not extend that code
to multiple tables. If you want to use multiple tables, you have to
create them first before calling addElementSegment.

The bulk memory operations should not bounds check ahead of time, but
instead should write as many bytes as possible until the first
out-of-bounds access.

We noticed that almost every call site were loading both files,
the split isn't necessary anymore.
In some message tests, removed the absolute line number to allow future
changes.

The table.copy bytecode copies a range of table entries in a similar
way to memcopy. This CL implements the behavior in a runtime call
that calls into the wasm engine.
