Ernest Wong aadae9242c Filestorage: Clone array views to avoid serializing full array buffer 
IndexedDB uses the StructuredSerializeForStorage algorithm to store
records into the database.

It appears that the html5 spec defines the StructuredSerializeForStorage
algorithm in a way that, when we serialize a TypedArray, the associated
ArrayBuffer is also serialized. Meaning even if the TypedArray is a view
of a single byte in the ArrayBuffer, the potentially-megabytes of data
in the ArrayBuffer are also copied over.

This makes sense. After deserialization, you'd expect the TypedArray to
function the same way as before meaning it should have the same
`.byteOffset` and `.buffer` properties.

However, it is easy to overlook this and think that a TypedArray viewing
2 bytes will only have the 2 bytes stored in the database.

This commit fixes a source of crashes. When calling
IndexedDBFileStorage#set() with a 3Mb file, the file is to be stored as
approx 800 lots of 4k blocks. However, in reality, 800 lots of 3 Mb array
buffers are being stored into the database. As the transaction is not
committed until the last request has been placed, I suspect that Chrome was
trying to store those 2.4 Gb worth of data in memory and did not handle
this case properly, leading to out-of-memory.

This commit also fixes a source of poor performance. When calling
IndexedDBFileStorage#read() to read 4k of a 48 Mb file, the browser seems
to be deserializing the entire 48 Mb into memory and garbage collecting
it even though only 4k is needed.

Fabian 23c5ebdf61 Reduce value of WASM_TABLE_SIZE and incraese JIT_THRESHOLD 
Now that WASM_TABLE_SIZE may be capped, we set it slightly below the
limit under which chromium crashes: https://bugs.chromium.org/p/v8/issues/detail?id=8427

JIT_THRESHOLD is also reduced due to two reasons:

- With the lower WASM_TABLE_SIZE, we want to avoid compiling too many
  modules
- It has occasionally been observed that under node, the engine's wasm
  compiler can't catch up with the number of modules we produce, thus
  resulting in 100s of pending compiled modules. This most likely
  happens only under node as we don't render the screen and
  the main loop (based on setImmediate) is faster.
  The new value doesn't seem to exhibit this problem, but we may want to
  increase the threshold further if the problem appears again

Fabian 0e16983dd3 Handle case when wasm table is full (fixes #35) 
Also fix jit_empty_cache when callbacks are pending (fixes #53)

This is also a preparation for setting WASM_TABLE_SIZE to a low value to
work around memory limitations in browsers.

Ernest Wong 83b283ebbe Filestorage: Replace the two server classes with a wrapper class 
Simplifies both the filestorage.js code as well as the starter.js code
that uses these FileStorage classes.

Now, the ServerFileStorageWrapper decorates the other FileStorage
classes by loading from the server when the file is not available.

Moreover, the previous starter.js was incorrectly passing the `baseurl`
parameter (it was passing it when baseurl was not defined nor needed).

Ernest Wong c2dcb440dd Filestorage: Refactor fallback and load-from-server 
Fallback logic is moved to the caller's responsibility.

Empty FileStorages and FileStorages that load from the server are
separated into different classes. This is to avoid faults where the
caller of the constructor forgets to pass in a `baseurl` parameter and
leads to some confusing bug.

- browser doesn't support indexedDB
- opening indexedDB fails
- existing database is a newer version
- existing database is an old version and is under use - blocking
current v86 instance to connect to it.

Fabian 0798a0b40e Don't create unnecessary entry points 
This commit prevents creation of entry points for jumps within the same
page. In interpreted mode, execution is continued on these kinds of
jumps.

Since this prevents the old hotness detection from working efficiently,
hotness detection has also been changed to work based on instruction
counters, and is such more precise (longer basic blocks are compiled
earlier).

This also breaks the old detection loop safety mechanism and causes
Linux to sometimes loop forever on "calibrating delay loop", so
JIT_ALWAYS_USE_LOOP_SAFETY has been set to 1.
