Nico Weber 4409b33145 AK: Make IndexSequence use size_t
This makes it possible to use MakeIndexSequqnce in functions like:

    template<typename T, size_t N>
    constexpr auto foo(T (&a)[N])

This means AK/StdLibExtraDetails.h must now include AK/Types.h
for size_t, which means AK/Types.h can no longer include
AK/StdLibExtras.h (which arguably it shouldn't do anyways),
which requires rejiggering some things.

(IMHO Types.h shouldn't use AK::Details metaprogramming at all.
FlatPtr doesn't necessarily have to use Conditional<> and ssize_t could
maybe be in its own header or something. But since it's tangential to
this PR, going with the tried and true "lift things that cause the
cycle up to the top" approach.)

Ali Mohammad Pur 7976e1852c AK: Ensure unions with bitfield structs actually have correct sizes
The fun pattern of `union { struct { u32 a : 1; u64 b : 7; }; u8 x; }`
produces complete garbage on windows, this commit fixes the two
instances of those that exist in AK.
This commit also makes sure that the generated unions have the correct
size (whereas FloatExtractor<f32> previously did not!) by adding some
nice static_asserts.

Ben Wiederhake f07847e099 Everywhere: Remove unused includes of AK/Concepts.h
These instances were detected by searching for files that include
AK/Concepts.h, but don't match the regex:

\\b(AnyString|Arithmetic|ArrayLike|DerivedFrom|Enum|FallibleFunction|Flo
atingPoint|Fundamental|HashCompatible|Indexable|Integral|IterableContain
er|IteratorFunction|IteratorPairWith|OneOf|OneOfIgnoringCV|SameAs|Signed
|SpecializationOf|Unsigned|VoidFunction)\\b

(Without the linebreaks.)

This regex is pessimistic, so there might be more files that don't
actually use any concepts.

In theory, one might use LibCPP to detect things like this
automatically, but let's do this one step after another.

Steffen Rusitschka 1aa07d7328 AK: Implement FloatExtractor<f128>
This patch adds support for 128-bit floating points in FloatExtractor.

This is required to build SerenityOS on MacOS/aarch64. It might break
building for Raspberry Pi.

Andreas Kling ae3ffdd521 AK: Make it possible to not using AK classes into the global namespace
This patch adds the `USING_AK_GLOBALLY` macro which is enabled by
default, but can be overridden by build flags.

This is a step towards integrating Jakt and AK types.

Jelle Raaijmakers 8483064b59 AK: Add FloatingPoint.h
This is a set of functions that allow you to convert between arbitrary
IEEE 754 floating point types, as long as they can be represented
within 64 bits. Conversion methods between floats and doubles are
provided, as well as a generic `float_to_float()`.

Example usage:

  #include <AK/FloatingPoint.h>

  double val = 1.234;
  auto weird_f16 =
      convert_from_native_double<FloatingPointBits<0, 6, 10>>(val);

Signed and unsigned floats are supported, and both NaN and +/-Inf are
handled correctly. Values that do not fit in the target floating point
type are clamped.
