Fix min/max signed zero and NaN handling.
Make min(x, y) equal to (x < y ? x : y) and max(x, y) equal to
(x > y ? x : y), including the behavior for signed zeros and NaNs.
This also enables optimizing them into min and max SSE2 instructions
on x86.

Fixing the Linux build without breaking the Mac build
This change adds 2 platform specific files for Linux, which
are used to define the typeinfo() functions used in some
classes in order to satisfy the ubsan compiler on Linux.
Unfortunately, adding those definitions on all platforms
breaks the build on Mac. Those aren't necessary on Windows,
so the Linux specific files are enough to make the build

Add dummy key methods for UBSan RTTI.
Chromium UBSan builds require RTTI, for which GCC/Clang requires each
class' first non-inline virtual method (the "key method") to have a known
definition so that its address can be used as a unique type identifier:
https://gcc.gnu.org/onlinedocs/gcc/Vague-Linkage.html
libEGL and libGLESv2 each use objects who's full definition only exists
within one or the other. Methods for which the definition is unknown can
still be called if they are virtual, because the compiler/linker only needs
to know the vtable entry offset. But because of the GCC/Clang requirement
of having the first non-inline virtual method be fully defined, we need to
add dummy virtual methods and their definitions.

Avoid vector element insert type mismatch.
Subzero silently allows inserting a 32-bit integer into a vector with
16-bit elements. This generates a pinsrd instruction, which requires
SSE4.1, even when specifying to only support SSE2. This change emits
a pinsrw instruction instead, which is SSE2.

Manually convert unsigned integer to floating-point.
Subzero uses a helper function to convert uint to float. It's faster to
just emit a sequence of operations to perform the cast manually.
This implementation converts the lower 31 bits as a signed integer, and
adds 0x80000000 as a floating-point value when the upper bit is set.
This approach does not produce the correct rounding in rare cases, but
should still be adequate. For consistency, we're also using this method
with the LLVM back-end.

Adding swiftshader unittests to chromium
Chromium does not allow any third_party code to depend on base,
so the main test runner for swiftshader's tests in chromium can't
live inside the swiftshader repo. To solve this:
1) Added a test environment for swiftshader that will be used
for testing in chromium. Currently, it is simply empty.
2) Split unit tests in 2 files, unittests.cpp, which will
contain the tests ran by both chromium and swiftshader and
main.cpp, which will be used as the swiftshader test runner,
but NOT as the chromium test runner (that one will be added
in chromium at the same time I do the swiftshader update).
3) The BUILD.gn file was updated to make the chromium version
of the test depend on base and on the chromium version of the
swiftshader test runner (swiftshader_tests_main.cc, to be added).

Deprecate support for constant pointers.
The use of constant pointers produces code that cannot be relocated.
They also cause issues in Subzero when offsetting them due to not having
constant folding support. We only used them for Direct3D cursor
rendering, which can just pass in the data as an argument instead.

Build fix
A few things needed to be fixed:
- Removed unused local variables in Sampler.cpp
- Local tests showed that newly added files for ubsan build fix
broke Mac and Windows builds. Moved files to Linux non debug
only to fix the issue on all platforms.

Renamed libEGL/Surface.* to libEGL/EGLSurface.*
In order to build libEGL without explicitly setting a dependency
on the Renderer and Reactor projects, the Renderer's Surface class
must be linked with libEGL. That was causing an issue where the 2
Surface.so objects were colliding on Linux. In order to solve the
issue, libEGL/Surface.* was renamed to libEGL/EGLSurface.*

Deprecate handling power-of-two texture sampling separately.
NPOT texture sampling is slightly slower, but with OpenGL we were
already treating every mipmapped texture as NPOT due to requiring
padding at the 1x1 level for renderability. Seamless cube maps are
also NPOT due to the border. Furthermore, the vector shifts by scalar
required for POT texel address calculation would require 128-bit
values when we deprecate MMX.
