This was being set to zero instead of one by mistake. Interestingly,
this was undetected by the CPU backend, but appears to matter sometimes
on the GPU side.

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.)

These cover new ground; when combined with some additional optimization
work, they can cause crashes in the optimizer that we don't see from any
existing test.

Every GPU API defines things this way, but C++ does not (until C++20).
Forcing the shift-as-unsigned prevents UBSAN warnings.

This lets us use descriptive names like `colorRed` and `colorGreen`
instead of `half4(1,0,0,1)` and `half4(0,1,0,1)`. It also lets us use
actual unknown values instead of synthesizing sorta-kinda-unknowns by
calling sqrt.

Comparing sqrt(5) against a variable containing sqrt(5) was not working
properly in some versions of Android running Vulkan.

This is a reland of 4ecab92584
This reland folds in subsequent code cleanups and disables a test that
failed on Android + Vulkan.
