There's no 64-bit ADD instruction, so we make do with ADD+ADC. This is
what Clang generates. ICC uses the two as well, but then performs some
subtractions to find out if it overflowed. GCC for some inexplicable
reason attempts to use SSE2 if that's enabled, otherwise it performs the
subtractions like ICC.
Alternative implementation which generates better code, but violates
strict aliasing:
uint *low = reinterpret_cast<uint *>(r);
uint *high = low + 1;
return _addcarry_u32(_addcarry_u32(0, unsigned(v1), unsigned(v2), low),
v1 >> 32, v2 >> 32, high);
Manual testing shows this works. tst_qnumeric passes in debug mode. MSVC
2017 15.9 still miscompiles in release mode (reported to MS as [1]).

When glyphs are converted to monochrome from an alpha map,
it does not make sense to apply high quality dithering, because
the result will be that some the subpixels along the edges
that cover only part of a pixel are filled. This causes the
glyphs to look jagged and ugly.
Instead, we use ThresholdDither to fill all pixels that are
>= 50% opacity.

When eliding text we would check for the existence of the ellipsis
character and fall back to using the dot if it was not available.
However, when font merging was in use, we would also use ellipsis
from a fallback font if available. This could cause the metrics
of the text to increase if the fallback font had larger metrics,
and the result was that text could shift when elided.
It is better to prefer the dot from the current font than to use
the ellipsis from a fallback, so we only use the ellipsis if
it is in the main font.

so we also allow the user to specify the location of the Windows Kit.
We also detect fxc on 64-bit hosts now, and in newer SDK versions which
version the binary directory.
The detected binary is now exported by configure, so the ANGLE project
