Ernest Wong a0c984dc8d Filesystem: Introduce IndexedDBFileStorage 
Uses MemoryFileStorage as a fallback when:
- v86 is used in a browserless environment, e.g. NodeJS
- 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.

Ernest Wong 595d6dca55 Filesystem: Refactor inodedata accesses to async methods 
The "// jshint ignore:line" comments are pretty messy, so squint your eyes.
They're systematically placed, so we can regex it out when jshint's
new version finally arrives.

Using async/await instead of callbacks due to callback hell, and it also
helps minimising the diff)

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.
