a51b2393f2 LibJS: Integrate iterator protocol into language features 
Finally use Symbol.iterator protocol in language features :) currently
only used in for-of loops and spread expressions, but will have more
uses later (Maps, Sets, Array.from, etc).

ef84865c8c LibX86+UserspaceEmulator: Devirtualize and inline more instruction code 
Use some template hacks to force GCC to inline more of the instruction
decoding stuff into the UserspaceEmulator main execution loop.

This is my last optimization for today, and we've gone from ~60 seconds
when running "UserspaceEmulator UserspaceEmulator id" to ~8 seconds :^)

2f81c20002 UserspaceEmulator: Move the SoftCPU stream virtuals to the header 
They don't actually get inlined yet, but at least this devirtualizes
them which is nice.

868db2313f LibX86: Apply aggressive inlining to Instruction decoding functions 
These functions really benefit from being inlined together instead
of being separated.

This yields roughly a ~2x speedup.

a27473cbc2 UserspaceEmulator+LibX86: Turn on -O3 optimization for emulation code 
Since this code is performance-sensitive, let's have the compiler do
whatever it can to help us with the most important files.

This yields a ~8% speedup.

8656835935 UserspaceEmulator: Add a very simple instruction fetch cache 
To avoid MMU region lookup on every single instruction fetch, we now
cache a raw pointer to the current instruction. This gets automatically
invalidated when we jump somewhere, but as long as we're executing
sequentially, instruction fetches will hit the cache and bypass all
the region lookup stuff.

This is about a ~2x speedup. :^)

c8d3f8cdeb LibGUI: Add Options flags and OpenMultiple mode for FilePicker

f266f0e880 LibGUI: Improve IconView performance with large selections 
This implements the following optimizations:

* Rather than clearing a HashTable of selected items and re-populating
  it every time the selection rectangle changes, determine the delta
  by only examining the items that might be in the area where the
  selection may have changed compared to the previous area. Then
  only add/remove selection items as needed.

* When painting, only query and paint the items actually visible.
  Also, keep a local cache of item information such as calculated
  rectangles and selection state, so it doesn't have to be calculated
  over and over again.

b778804d20 LibGUI: Add ModelClient abstract class and allow registering clients 
This solves a problem where the SortingProxyModel doesn't
receive the on_update call because other code overwrote
the handler later on.

46661f02c6 Csilla: Make 'W' and 'w' even thinner 
'W' doesn't have to go up to the edges which makes 'WWW'
look better, and it imho looks fine in other contexts too.
Update 'w' to match.

Don't change Katica since it has enough room for the current W.

151e4d41ed Shell: Put children in their own process groups and fix job control 
This commit fixes job control by putting children in their own process
group, and proxying TTY signals to active jobs.
This also cleans up the code around builtin_disown a bit to use
the newer job interfaces.

6a265f7c21 unzip: mmap() the zip file if possible to avoid spamming syscalls 
This patch makes `unzip' mmap the zip file instead of seeking the file
repeatedly.
This makes unzipping big files bearable, and unzipping huge files
impossible.
The later could be fixed by mapping/unmapping chunks on the fly once we
have support for mmap() offsets.
