This makes it more inline with its currently unavailable standardized
analogue std::derived_from.
While we're at it, we can also make the template match the requirements
of the standardized variant as well.
Previously the constructor for all of these would run at program
startup, consuming time before the application can enter main().
This is also particularly dangerous, given the logging system wouldn't
have been initialized properly yet, yet the program would use the logs
to signify an error.
To rectify this, we can replace the literals with constexpr functions
that perform the conversion at compile-time, completely eliminating the
runtime cost of initializing these arrays.
On DragonFly and NetBSD build fails with
src/common/virtual_buffer.cpp
src/common/virtual_buffer.cpp:16:10: fatal error: sys/sysinfo.h: No such file or directory
#include <sys/sysinfo.h>
^~~~~~~~~~~~~~~
* ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer
With the support of C++20, we can use concepts to deduce if a type is an STL container or not.
* More agressive concept for stl containers
* Add -fconcepts
* Move to common namespace
* Add Common::IsBaseOf
In file included from src/core/hle/kernel/memory/page_table.cpp:5:
src/./common/alignment.h:67:68: error: no member named 'align_val_t' in namespace 'std'
return static_cast<T*>(::operator new (n * sizeof(T), std::align_val_t{Align}));

In cases where the size is not a known constant when inlining, AlignUp<std::size_t> currently generates two 64-bit div instructions.
This generates one div and a cmov which is significantly cheaper.
This is a new attempt at #4206 that shouldn't break windows builds.
If someone else could test on windows, it would be much appreciated.
Previously, the build bot passed but the actual builds failed.
On gcc/ld, and clang/lld, fmt::v6 symbols are excluded, so linking
fails. This fixes the issue.
Note: This was included in the FindBoost changes I shared with
BlinkHawk, however only they were merged. I'm not sure if it was missed,
or if there was an issue with this part of the change.
This commit: Implements CPU Interrupts, Replaces Cycle Timing for Host
Timing, Reworks the Kernel's Scheduler, Introduce Idle State and
Suspended State, Recreates the bootmanager, Initializes Multicore
system.
