ANGLE has moved onto the Windows 10 SDK, and is using new compiler
features that aren't supported by the old Windows 8.1 toolchain. Support
for the 8.1 projects has been broken in master for some time now.

Since more and more developers are moving towards Windows 10, we
are going to take a snapshot of ANGLE that includes 8.1 support and
freeze it in a branch on github.com/microsoft/angle. If developers
wish to compile for use ANGLE in 8.1 apps then they should use that
branch going forward.

The 'LoadToNative' copy is the only one that should be considered a
non-conversion. For depth formats, we should be clamping on SetData
and CopyImage calls, so this changes the flags for two of the
depth formats, but won't affect behaviour since the conversion bit
is never check for depth/stencil formats.

This allows us to remove the 'requiresConversion' bit from the data.

Most error checking functions in ParseContext used to follow a format
like <property>ErrorCheck. Sometimes this function would check that
the node/value would have <property>, sometimes it would check that
the node/value would not have it, which was confusing. Change most of
these functions to use a lot more descriptive names, which clearly
communicate what they are checking for.

Also includes a bit of refactoring in constructorErrorCheck(), so that
the function only checks for errors rather than also setting the type
of the constructor node.

Also make TType::arraySize unsigned, and return a sanitized size from
checkIsValidArraySize() instead of using an output parameter.
