This fixes the following case:
<blockquote>

Qt would see the end of <span>, and consider the current block
tag as closed, thus resetting the block format, thus losing the
margin set for the current block (due to blockquote).
If you do

instead, then the same would not happen, since hasBlock is set

The DSA emulator functions query which texture is currently bound
to a given target, then bind the new one, perform an operation,
and bind the old one back.
The problem is that in order to query what's currently bound to the
GL_TEXTURE_<X> target one needs to call glGetIntegerv passing
GL_BINDING_TEXTURE_<X>. Since both GL_TEXTURE_X and GL_BINDING_TEXTURE_X
values are completely arbitrary (not contiguous nor related in any way)
we need to pass *both* them to the functions.
The right GL_BINDING_TEXTURE_X was getting already chosen (and stored)
at texture creation time by QOpenGLTexture, so it's just a matter
of passing it around.
For the "real" DSA functions, the binding target is ignored.

Also, the two lastIndexOf and the qt_find_latin1_string updates are also
fixing bugs because the old code forgot to cast the input to uchar
first. That meant the compiler was generating sign-extension from 8 to
16 bits, as opposed to zero-extension.

Decoding from UTF-8 is easy: if the high bit is set, we fall back to
the byte-by-byte decoding. Encoding to UTF-8 requires a little bit
more work: to detect anything between 0x0080 and 0xffff, we have
several options but none as easy as above. Multiple alternatives are
in the benchmark code.
In both loops, we do two things once we run into a non-ASCII
character: first, we continue the loop for the remainder of ASCII
characters in the buffer (which we can tell by checking the bits set
in the mask), then we find the last non-ASCII character in that
16-character group, so we don't reenter the SSE code too soon.
For the UTF-8 encoding, I have chosen the alternative that results in
the best performance. It's closely tied to the alternative running the
PMIN instruction, but that requires SSE 4.1. It's not worth the
complexity. And quite counter-intuitively, the dedicated string
instruction from SSE 4.2 performs most poorly of all solutions. This
begs re-visiting the performance of the toLatin1 encoder.
The best of 10 benchmark runs of this code were measured on my
SandyBridge CPU @ 2.66 GHz (turbo @ 3.3 GHz), both as CPU cycles and
as CPU ticks:
Compared to: ICU Qt 4.7 non-SSE Qt 5.3
Data set fromUtf8 toUtf8 fromUtf8 toUtf8 fromUtf8 toUtf8
ASCII only 7.50x 6.22x 6.94x 7.60x 4.45x 4.90x
2-char UTF-8 1.17x 1.33x 1.64x 1.56x 1.01x 1.02x
3-char UTF-8 1.08x 1.18x 1.48x 1.33x 0.97x 0.92x
4-char UTF-8 1.05x 1.19x 1.20x 1.21x 0.97x 0.97x
Creator data 3.62x 2.16x 2.60x 1.25x 1.78x 1.23x
As shown by the numbers, the SSE-based code is slightly worse than the
non-SSE code for dense non-ASCII strings. However, as evident in the
Qt Creator data, most strings manipulated by applications are either
pure ASCII or mostly so, so there's a net gain.
