Getters for GrFragmentProcessor's optimization flags and state are
exposed as constant fields on the fragmentProcessor variable in sksl.
The CPP code generation then emits extra instructions to invoke the
particular getter when building the final sksl string at runtime.

The previous implementation of flushEmittedCode(), that flushed on
demand when a process() was encountered, was brittle and susceptible to
mangling the expected sksl when fOut was modified outside of its
control. Given that writeFunction() and generateCode() in the parent
class all do this, it's possible to generate a simple SkSL snippet that
would generate a CPP file that builds invalid final SkSL:
```
in fragmentProcessor child;
bool someGlobalVar = ...;
void main() {
if (someGlobalVar) {
sk_OutColor = process(child, sk_InColor);
} else {
sk_OutColor = half4(1);
}
}
```
The CPP generated code *should* insert 'bool someGlobalVar' at the start
but because of the early flush from the child process and because of
how fOut was overwritten, someGlobalVar's declaration is put into a
stream that is not visible to the flush and ends up being inserted into
the output sksl in an incorrect location (namely after the if condition
that depends on it).
This CL updates the extra emitted code logic to support multiple blocks
of extra CPP code. When a flush point occurs in SkSL writing, a special
token is inserted into the SkSL and a new CPP code buffer is associated
with that token. Then once all of the SkSL is accumulated into the root
output stream, it is processed into sections for each extra CPP block.
Special logic is done so that the SkSL that is emitted before the next
CPP block terminates at the end of the last valid statement before the
special token.
A unit test demonstrating this failure condition is added to SkSLFPTest
and the CL properly passes. Since this bug did not trigger on existing
.fp files, the updated generator does not modify the generated FPs.

Easily supports mapping ctypes to sksl types with templates that
specify how to send data to the GPU and how to track state changes.
The template logic and type mappings are defined in
SkSLCPPUniformCTypes.* while SkSLCPPCodeGenerator is updated to
utilize it.
It also updates the supported ctypes to properly generate code for
SkPoint, SkIPoint, SkIRect, and GrColor4f. The code generated for
'in uniforms' now also correctly supports conditional uniforms.

This expands sksl's capabilities with .fp files. Previously, it was possible to declare "in fragmentProcessor foo" and emit it automatically when "process(foo);" was called. This adds a variant of process that takes a second argument, which must be a half4 expression. This argument specifies the value, or dynamic expression calculated earlier in the parent shader, to use as sk_InColor by the child.
The CL is longer than anticipated because of properly handling dependencies between previous sksl statements and the input to the child. The original writeEmitCode() collected all extra emission code (the calls to build->emitChild) and put them before any call to codeAppendf. This makes it impossible to use a parent's variable, or the output of another child, as the input for process.
To solve this, there is now a flushEmittedCode() function that takes over the logic of outputting the extra emission code and the necessary codeAppendf calls. When invoked, it (by default) only appends completed sksl statements, and places any current expression back at the beginning of the output stream. It now updates fFormatArgs and fExtraEmitCodeCode as it consumes their contents. This allows writeFunctionCall() for a call to "process" to flush all previous statements before it adds its emit child code.

Most of this is (obviously) not necessary to do, but once
I started, I figured I'd just get it all. Tools (nanobench,
DM, skiaserve), all GMs, benches, and unit tests, plus support
code (command line parsing and config stuff).
This is almost entirely mechanical.

Auto-allocated IDs mean that the IDs depend upon the order in which
classes happen to get initialized and are therefore not consistent
from run to run. This change paves the way for a persistent shader
cache by fixing the IDs in an enum.

The ultimate goal is to end up with "float" and "half", but this
intermediate step uses "highfloat" so that it is clear if I missed a
"float" somewhere. Once this lands, a subsequent CL will switch all
"highfloats" back to "floats".

On desktop, this saves just over 5% of the time in the SkSL compiler.
As written, the code will now build either way, so it's much easier to
switch back (or even have some platforms use SkString, if that's ever
required).
