These functions were functionally almost identical, except:
- Sometimes sda/dsa are flipped
- Sometimes the saturation is not updated
We now have one method (blend_hslc) which can do all four blend
operations. It takes two new parameters ("flip" and "saturate") to
handle these four variations.
This reduces our shader count on some of our most shader-heavy slides
(e.g. aaxfermodes, xfermodeimagefilter) at a pretty reasonable cost.

This saves a significant amount of CPU time and, now that the inliner
can handle nested expressions, still inlines almost everything.

Arguments without side-effects that aren't read from more than once can
be moved directly into the inlined function, and don't need a scratch
variable. This can allow functions like `guarded_divide` to inline
completely in more cases.

I ran into an issue in an upcoming CL which generated a particularly
ugly switch statement:
switch (x) {
default:
discard;}
So I cleaned this up, and while resolving this issue, managed to improve
a bunch of existing codegen as well. The formatting change has been
split out to a separate CL since it impacts so many golden outputs.

These variables were later being eliminated by the dead-code-elimination
pass, so you can't see them directly in the final output, but removing
them affects the name mangling off all future symbols, so it causes an
enormous ripple effect in the diff. And of course, it's a waste of time
and memory to synthesize IRNodes just to destroy them later.
If we disable control-flow analysis, we lose the dead-code-elimination
pass entirely; this change is also beneficial for emitting better code
when optimizations are turned off.
