fa6a127310 Large simplification of the CType mapper logic in SkSL
- Arrays were unused
- Each ctype was used with exactly one mapper - remove the SkSL type
  list
- After that, the mapper was just a key + value, so make it just a value
  and use a map (rather than vector)

420c563ba1 Add support for uint types in DSL C++ code generation.
UInt support was added to DSL in http://review.skia.org/403601. We use
the UInt type in the DitherEffect fragment processor.

115645ee9b Evaluate various single-argument float intrinsics at compile time.
This CL only handles a subset of our intrinsics. In particular, it
avoids changing the behavior of `sqrt` as many of our tests use sqrt as
an optimization barrier.

The transcendental test inputs are intentionally kept very simple to
avoid putting numbers in the test outputs which could round differently
on various platforms and cause Housekeeper to complain.

bf3e9e9591 Remove sample-with-matrix from SkSL

with matrix transforms on child sampling. Removing this makes everything

c4e9588621 Improve DSL CPP support for global variables.
Global variables which can be calculated in C++ code are now written as
constant values in the DSL, instead of performing the same logic
redundantly in the shader.

In some cases this can be fairly significant, e.g. RectBlurEffect has
a global with the expression
    abs(rect.x) > 16000 || abs(rect.y) > 16000 ||
    abs(rect.z) > 16000 || abs(rect.w) > 16000

d6e1e0fb46 Use macros for sk_Caps again.
This undoes the change from http://review.skia.org/400541 and reworks
sk_Caps to use macros, exactly like the existing CPPCodeGenerator.

This compromise is necessary for when-expressions. Specifically, when-
expressions must be valid when parsed *either* as SkSL or as C++. We
want to support when-expressions that reference sk_Caps, like:

    layout(when=!sk_Caps.floatIs32Bits)

The macro approach allows this when-expression to work.

ec871bf353 Fix global variables which call built-in functions.
When emitting a built-in function call, we need to honor the `fCPPMode`
state. Previously we were rewriting the call into a DSL call even in C++
mode.

We also now spell out Fract's complete namespace, to avoid a name
collision with MacTypes.h:

https://opensource.apple.com/source/CarbonHeaders/CarbonHeaders-18.1/MacTypes.h.auto.html
    typedef SInt32                          Fract;

b9fc6e45c2 Support 'layout(when)' expressions in DSL C++.
This required some changes to how we name variables in DSL.
When-expressions are designed to expect a local C++ variable with the
same name as the layout key. This constraint means our DSLVar variables
CANNOT have the same name as the layout key. Now, all DSL variables are
given a prefix. We try to keep the code tidy by using just a leading
underscore as the prefix, where it's safe to do so. (The C++ naming
rules put some underscore-names out of bounds, but underscore followed
by a lowercase letter is safe.)

08c6608907 Append f suffix to float literals in DSL C++.
This prevents some ambiguous-expression errors (since we were passing a
`double` typed value into places that only took an `int` or `float`).

(The ambiguous-expression errors were later fixed in
http://review.skia.org/400619, but it's still the right thing to do for
DSL C++ to emit floats.)

16cbfb41df Implement statements and expressions in DSL C++ code generator.
This CL removes the bulk of the existing C++ code generator, especially
all the complex format-string assembly code. It has been replaced with
actual DSL code generation. Simple IR can now be successfully translated
to a working DSL fragment processor.

This CL also adds a simple test harness which is patterned after the
existing SkSLTest; it renders a pixel, reads it back, and fails the test
if the result isn't solid green (RGBA=0101).

This CL doesn't implement every feature. Some obvious gaps include:
- Sampling from children
- Uniforms/inputs of any kind
- Function calls of any kind
