When sampling an sRGB texture format, we have a vector of 16-bit
elements where 0xFF00 represents 1.0, but we were using a lookup table
which produced results in a 0xFFFF base.

Also on linear to sRGB conversion, precision was lost due to truncating
to 12-bit. Adding a rounding factor before truncating preserves
precision.

This works well as our use-case is to lookup the same addresses multiple
times (loops, helper functions, etc.). With a simple timing of
ReactorUnitTests.exe, with this optimization enabled, total time dropped
from 16.72 seconds to 2.24 seconds (~7.5X faster).

This optimization is especially important for Mac where resolving stack
addresses takes much longer than on other platforms. With this
optimization, running a specific gles-unittests test, it was able to
output the callstack trace in about 30 seconds; without, it was still
emitting jit code after 10 minutes at which point I gave up.

When I (hack) fixed the fact that Subzero fails to load from a constant
source because it interprets it as an offset, I did so by routing all
loads into sz::createLoad, and in there, making sure to bitcast constant
sources to variables. I thought this covered all loads, but it turns out
that one of our optimization passes optimizes stores by removing
intermediate stores. This would sometimes replace a variable source with
a constant one, so I applied a similar hack here to avoid doing replace
in this case.
