Turns out a simpler way was added to the docs at some point and I never
noticed.
Before:
text data bss dec hex filename

After:
text data bss dec hex filename

We already have an equivalent header within FEXCore that's header only,
so we can adapt it to conform for both cases, allowing for removal of
one of them.
Moves the IR include into one of the more specific headers, which avoids dumping the IR header into any core bits that use the interface.
Also uncovered a missing header guard.
We definitely don't want the boolean null test to be able to be implicitly converted
(e.g. to an int or whatever else).
For example a non-explicit bool operator allows for silly things like:
NonMovableUniquePtr<...> ptr;
// ...
auto k = 5 + ptr;
to build without issue, which we should really force the user to be explicit about if it's *really* a desired behavior.
We can reduce includes, such as logging by specifying a concrete size for logging levels,
allowing the enum to be forward declared. We can also move FillHeader into the cpp file,
allowing the syscalls header to be removed.
Since all of the information comes from the Dispatcher, we can have the dispatcher
provide that information. This way we can also eliminate a bunch of now-redundant
public interface members and simplify the config setup within InitCoreImpl().
Conveniently, this also allows making all members of the dispatcher non-public.
The name itself is already qualified with SignalDelegator, so this can reasonably be outside the class itself.
This also allows for forward declarations of the config struct
A prevalent pattern in the FEX codebase is to compute some data and store it
in a maybe_unused variable that's only ever passed to LOGMAN_THROW_A_FMT.
Besides few exceptions, we never compute expensive data in the macro
arguments themselves, so we can remove a lot of code noise by unconditionally
evaluating the condition even in assertion-disabled builds.
Taking this very slowly because this is very fickle code. The frontend
needs to manage GDT and LDT, but before we get there, we need to
actually add support for LDT in the backend. Split the segments to two
arrays so the JIT can actually update their cached values correctly.
Still treats GDT and LDT as mirrors like how the JIT previously did (By
it ignoring the selector's TI bit).
