In the majority of cases, a uniform is an equally good substitute, and
replacing `sqrt(N)` with `unknownInput` actually makes the test clearer.

A cast like `float(five)` or `int4(colorGreen)` should detect const
variables and replace the expression with its compile-time constant
equivalent value. At present, this replacement is missed, which inhibits
further optimization opportunities on the expression.

Previously, the code neglected to resolve constant variables into
values. This meant that expressions like `lessThan(zero, one)` could not
be compile-time evaluated even when `zero` and `one` have known values.

If every argument passed to any() or all() is a compile-time constant,
we now detect this and optimize away the function call entirely.
Future CLs will perform a similar optimization on other intrinsic calls
which can be detected and eliminated at compile time, like lessThan().

This shook out a long-standing bug; constant folding would treat a
matrix resize as if the cells not covered by the original matrix were
all zero. This is wrong; GLSL populates the unknown cells with an
identity matrix. We actually tested for the wrong behavior, so the tests
were updated to match the correct behavior, and an equivalent test was
added that does not constant-fold (to verify that our constant folder
matches reality).

We don't directly support this today at all. In practice, though, simple
constant arrays are detected as equal in the constant-folding pass
because they hit the `x == x` self-equality check (using
`IsSameExpressionTree`).
This does not work for our inequality tests, though, so those do not
fold.

Currently, SkSL is able to constant-propagate `x = x + constant` into
`x = constant` when the starting value of x is known. However, it is not
able to do the same optimization for `x += constant`. This test
demonstrates that once += is encountered, we lose track of x's value and
can no longer propagate its value.
(This is equally true of all the op-assignment operators, += -=
*= /= etc.)
