This adds unit tests for IOS/ESFormats, and in particular, for the
TMDReader. It is tested using invalid TMDs (to check IsValid()) and
two valid, properly signed TMDs.
Things which are now tested:
* Title type helper functions.
* TMDReader: Validity check.
* TMDReader: General information returned by the Get*() methods.
* TMDReader: Raw TMD and generated TMD view, compared against IOS.
* TMDReader: Game ID generation code (which is Dolphin specific).
* TMDReader: Content information: getting by ID/index, order, metadata.

This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
This attempts to make some bit arithmetic more self-documenting and also
make it easier during review to identify potential off-by-one errors by
making it possible to just specify which bits are being extracted.
Functions both support the case where bits being extracted can vary and
fixed bit extraction. In the case the bits are fixed, compile-time asserts
are present to prevent accidental API usage at compile-time.
e.g. Instead of shifting and masking to get bits 10 to 15,
Common::ExtractBits<10, 15>(value) can just be done instead.
Jan 04 22:55:01 <leoetlino> fwiw, it looks like there are new warnings in the RegCache code
Jan 04 22:55:04 <leoetlino> Source/Core/Core/PowerPC/Jit64/FPURegCache.cpp:13:33: warning: declaration shadows a variable in the global namespace [-Wshadow]
Jan 04 22:56:19 <@Lioncash> yeah, the jit global should have a g_ prefix.
This fixes shadowing warnings and adds the g_ prefix to a global.
The min-heap provides no ordering when the key is the same on 2
nodes. Disambiguate identical times by tracking the order items
were added into the queue.
MSVC's implementation of numeric_limits currently generates incorrect
signaling NaNs. The resulting values are actually quiet NaNs instead.
This commit is based off of a solution by shuffle2. The only
difference is a template specialization for floats is also added
to cover all bases
Approximately three or four times now, the issue of pointers being
in an inconsistent state been an issue in the video backend renderers
with regards to tripping up other developers.
Global (ugh) resources are put into a unique_ptr and will always have a
well-defined state of being - null or not null
