Ernest Wong 644d2cfca8 Filestorage tests: Improve mock transaction lifetimes 
- Assert that transaction operations are done within their callback
scopes.
- Improve test performance by using setImmediate for queueing macrotasks
instead of using setTimeout.
- Check for in-progress callbacks before completing transactions.

Note that promise callbacks are run as microtasks. When request
onsuccess callbacks are run, the transaction becomes active again and allows
further requests to be placed against that transaction. The transaction
becomes inactive when the program reaches the end of the event loop
iteration. However, all microtasks are exhausted before the event loop
iteration ends, so the transaction remains active even within the promise
callbacks.

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.

Ernest Wong c7dda46de1 Filesystem: Disallow hardlinks across filesystems 
Although hardlinks across filesystems worked quite well in the current
implementation, we will run into problems when we try to implement
different backends for each sub-filesystem.

Note: EPERM is used instead of EXDEV since the mv command will silently
try to use copy-and-unlink when rename(2) fails with EXDEV.

The rules for linking has been reverted back:
 - Before commit: Any inode, including forwarders, could be linked as
long as the parent is not a forwarder and is a directory.
 - After commit: Only non-forwarders and root-forwarders are allowed to
be linked, and must be linked under a directory and not a forwarder.

Ernest Wong 4a76c66ff3 Improve tests for fs.Rename across mounts 
- Test both file and directory.
- Test combinations of forwarder/non-forwarder source/destinations
- Test different destination filenames
- Test empty file

Can't test early failure behaviour when destination can't be unlinked,
since right now only non-empty directories and root directories can't be
unlinked and busybox's mv program does not support mv
--no-target-directory.

Ernest Wong 070c38c6a1 Add tests for host-side fs mounting 
The testing "framework" code is slowly turning into spaghetti due to the
asynchronous nature of the triggers. Using async functions will help
clarify the program flow if we think we should address this issue.

- jit_cache_array
- page_first_jit_cache_entry

Other miscellaneous changes:
- Page is an abstract type

- Avoid use of global state wherever possible
- Delete string packing
- Make CachedStateFlags abstract
- Make AnalysisType product type
- Make BasicBlockType product type
- Restore opcode assertion
- Set opt-level=2 in debug mode (for test performance)
- Delete JIT_ALWAYS instrumentation (now possible via api)
- Refactor generate_analyzer.js
- Refactor generate_jit.js

Ernest Wong 2bb5b194dc Fix virtio 9p tests 
I wrongly assumed that libv86 would perform faster than libv86-debug.
Using libv86 caused ttyS0 to timeout before initialising, so there was
not serial terminal to use by the time debian booted.

Ernest Wong fe40ebc0f8 Add tests for virtio 9p (tests are currently incorrect) 
These tests do not work yet: it fails to capture the serial output
after root login.

In addition, these tests are currently too slow to run
since it takes a while to boot the debian image (> 16 minutes on my
machine while running the test in the terminal.)

Would need to switch to a newer minimal linux image when available.
