57dc179b1f Everywhere: Rename to_{string => deprecated_string}() where applicable
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.

One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.

6e19ab2bbc AK+Everywhere: Rename String to DeprecatedString
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)

42e22f89a4 AK+LibGfx+LibJS: Pass -1 as the file descriptor to anonymous mmap
Serenity/Linux/macOS ignore the file descriptor when an anonymous
mapping is requested. However, BSDs require the fd to be -1.

1414c7b049 LibJS: Add a basic pass manager and add some basic passes
This commit adds a bunch of passes, the most interesting of which is a
pass that merges blocks together, and a pass that places blocks that
flow into each other next to each other, and a very simply pass that
removes duplicate basic blocks.
Note that this does not remove the jump at the end of each block in that
pass to avoid scope creep in the passes.

d560ee118d LibJS: Allocate 4 KiB for Bytecode::BasicBlock
There's no reason not to, since we're using mmap() for these anyway
and that gives us memory in 4 KiB increments. :^)

6a0d1fa259 LibJS: Store strings in a string table
Instead of using Strings in the bytecode ops this adds a global string
table to the Executable struct which individual operations can refer
to using indices. This brings bytecode ops one step closer to being
pointer free.

01e8f0889a LibJS: Generate bytecode in basic blocks instead of one big block
This limits the size of each block (currently set to 1K), and gets us
closer to a canonical, more easily analysable bytecode format.
As a result of this, "Labels" are now simply entries to basic blocks.
Since there is no more 'conditional' jump (as all jumps are always
taken), JumpIf{True,False} are unified to JumpConditional, and
JumpIfNullish is renamed to JumpNullish.
Also fixes #7914 as a result of reimplementing the loop logic.
