e122502f70 AK: Speed up BitmapView::find_next_range_of_unset_bits 
While watching Andreas' most recent video, I noticed that this function
only worked with 32 bit values, but was a serious performance
bottleneck for the kernel. As such, I reworked it to use `size_t`, so
it now can switch to 64-bit sweeps on 64-bit platforms. This caused
test-js to go from 12.5 seconds hot to 11.5 seconds hot on my machine
when running on KVM x86_64.

548529ace4 AK: Add BuiltinWrappers.h 
The goal of this file is to enable C++ overloaded functions for
standard builtin functions that we use. It contains fallback
implementations for systems that do not have the builtins available.

1f2d0d0ad4 Kernel: Use ksyms in-place instead of duplicating them into eternal heap 
We can leave the .ksyms section mapped-but-read-only and then have the
symbols index simply point into it.

Note that we manually insert null-terminators into the symbols section
while parsing it.

This gets rid of ~950 KiB of kmalloc_eternal() at startup. :^)

d5dce448ea AK: Bypass Buffered's buffer for large reads 
Before, if we couldn't read enough data out of the buffer, we would re-
fill the buffer and recursively call read(), which in turn reads data
from the buffer into the resliced target span. This incurs very
intensive superflous memmove's when large chunks of data are read from
a buffered stream.

This commit changes the behavior so that when we exhaust the buffer, we
first read any necessary additional data directly into the target, then
fill up the buffer again. Effectively, this results in drastically
reduced overhead from Buffered when reading large contiguous chunks.
Of course, Buffered is designed to speed up data access patterns with
small frequent reads, but it's nice to be able to combine both access
patterns on one stream without penalties either way.

The final performance gain is about an additional 80% of abench decoding
speed.

a409b832fa AK: Make JsonValue::from_string("") return a null JsonValue 
This unbreaks the /var/run/utmp system which starts out as an empty
string, and is then turned into an object by the first update.

This isn't necessarily the best way for this to work, but it's how
it used to work, so this just fixes the regression for now.
