Currently when the build executes it copies things like .so files and
the vulkan .icd file to the CMAKE_CURRENT_SOURCE_DIR/out/<platform>
directory. This is fine in a normal swiftshader build but if you embed
swiftshader into another project this ends up being something like:
third_party/swiftshader/out/<platform> which is not what is desired.

This CL changes the files to get written to the CMAKE_BINARY_DIR. This
means it will go into the directory form which cmake was run. This means
for a build setup as per the README, build/<platform>.

This also allows generating different .icd and .so files for Release and
Debug if you setup different build directories.

D16_UNORM depth operations are performed in fixed point to avoid quirks
of ushort <-> float roundtrip

Some slight oddities to work around missing primitives:
- We only have CmpEQ, CmpGT. This matches SSE hardware reality.
  Everything else is made out of negations and operand swaps.
- We only have *signed* CmpGT. Make an unsigned CmpGT by biasing both
  16-bit operands by -0x8000.
- In non-quad-layout we don't have a good way to separate .xy and .zw
  halfs; reading via masked short4 reads, writing via individual
  component writes.
