- Comparing A==B will return true for NaN depending on the FP mode, so we now compare if both values are finite before comparing for equality.
- This does not fix the source of the error, but will stop all subsequent float values being set to NaN

- Remove the condition causing SCW to automatically exit after a single job if HLSLcc was used. This doesn't appear to be beneficial; HLSLcc uses a lot of memory but does not appear to leak it, so we're wasting time spinning up new processes unnecessarily here. This allows us to deprecated the associated field in the compiler output and function in IShaderFormat.
- Strip out compiler invocations stats; this was not accurate in some cases and it was decided after discussion that at this point the effort to fix the problems was not worth the utility we get from it.

B = A;
A = GetSecondValue();
C = A; // <-- this would get GetSecondValue() assigned to C instead of GetFirstValue()
Adds an SSA pass to help reduce overwriting registers, adds logic to remove self assignments, and adds logic to stop propagating when values are dirtied
From a sampling of scripts, about 2% are changed (where 1-3 unnecessary ops have been deleted).
