It makes inspector tests a lot more readable if the opcode of the pause
location is being printed. Since we already have a list of all opcodes
available in wasm-module-builder.js, we can just reuse that to build a
reverse lookup map.
This CL implements this for single-byte opcodes only, which is enough
for all tests that we currently have. It will have to be extended for
prefixed opcodes once that is being used.

This is a minor cosmetic fix. Wasm opcodes are bytes, hence they should
always be printed as an even number of hexadecimal digits.
Note that currently we only print a single byte anyway, but in the
future we will want to extend this to correctly parse multi-byte
opcodes. Those will also be printed as an even number of characters
then.

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.

Inspector will no longer report per-function wasm scripts or
provide wasm disassembly. Locations in wasm are now consistently
reported through the inspector API as lineNumber=0
columnNumber=byte offset in module.

Currently, in wasm-function stack traces, v8 displays the decimal offset
from the start of the function. However, the WebAssembly WebAPI
specification says that it should be a hex offset into the module.
This change makes the stack trace display with hex module offsets, as
well as fixing all the unit tests that depended on the old behaviour.

This refactoring makes it easier to write advanced tests and
gives full control over what's happening to the test code.
It also forces description for every test.

In Isolate::CaptureSimpleStackTrace, we were ignoring interpreter entry
frames so far. This CLs changes this to gets the interpreted stack from
the wasm interpreter and add the frames to the FrameArray.

If the imported wasm function is being debugged (i.e. redirects to the
interpreter), call it via the JS_TO_WASM stub, such that we can disable
the breakpoint later by patching the exported function.
This also contains a drive-by fix in wasm-translation.cc (for the case
that all known positions are bigger than the requested one).
