Surprisingly, this actually improved our error detection slightly.
The expression `- -half4(0)` can now be simplified to `half4(0)` at
IR generation time, which allows the constant-folder to detect a
constant zero (and from there, a division by constant zero).

Fundamentally this function wasn't a generic "set the refKind on an
expression" at all; it was intended specifically as "this expression
must be IsAssignable and contain a VariableReference." Also, it needs
nothing at all from the IRGenerator. Moving it out is important because
it will be used by Make functions for things like VariableReference.

This adds Analysis::IsConstantExpression, to determine if an expression
is a constant-expression. It now expands to cover 'const' local and
global variables, because we also enforce that the initializer on those
variables is - in turn - a constant expression.
This fixes 10837 - previously you could initialize a const variable with
a non-constant expression, and we'd emit GLSL that contained that same
pattern, which would fail to compile at the driver level. That should
not be possible any longer.

While working on an unrelated fix, I noticed that Ossfuzz28904.sksl has
an expression which generates a constructor of $literal type: `-2 .L1`
This shouldn't ever happen, so the code is now fixed to avoid it. This
doesn't affect any of the output from our existing tests. (In that
oss-fuzz test, that literal constructor is immediately expanded out to
an ivec2 by the swizzle, at which point it loses its $literal status
anyway.)

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.
