ab0a13d9d9 Removed the final remnants of IRGenerator
This completes the long process of moving all of IRGenerator's code and
data into better homes and finally kills the class altogether. There is
a lot of #include churn here due to poor header hygiene in the past;
IRGenerator.h included a ton of stuff and almost everything included
IRGenerator, allowing us to inadvertently be sloppy with our includes.

72602b668e Enable matrix tests on viable platforms.
A handful of older drivers choke on weird matrix construction layouts.
The tests have been disabled on those bots. The GLSL docs and
conformance tests make it clear that such ctors were intended to work,
even if the drivers don't necessarily handle them properly.

`textureCube` was in our list of built-in types, but was not actually

64c907c052 Mark private types as invalid in the public symbol table.
Previously, in public code, private types didn't exist anywhere in the
symbol table chain, and those names were free for the taking. Now, we
register them as invalid types in the public symbol table. This prevents
them from being used as variable names, and gives a more explicit error
if you try to use them as a type.

5420cbcf65 Match GLSL scoping rules more closely in SkSL.
GLSL treats builtin types and user-defined types differently; `int` and
`float` are keywords and cannot be used to name variables. However, it's
fine for a user type like `struct xyz` to be hidden by a variable
`int xyz` or even `xyz xyz` (i.e., a variable of type `struct xyz` named
`xyz`).

We now honor that distinction and include tests for it. This will fix
several ES2 conformance tests (local_struct_variable_hides_struct_type,
local_int_variable_hides_struct_type, etc.).

116d2e0e48 Fix ES2 conformance test 'in_vs_no_in'.
SkSL treated these two functions as distinct, even though they are not:
    void func(in float x);
    void func(float x);

The `in` modifier on a function parameter is the default state, making
these two prototypes functionally identical. We now strip off an `in`
modifier on a function definition. This gives us three potential states
for each param: nothing (meaning `in`), `out`, and `inout`.

9fa47cc1c6 Make class members that are static constexpr also be inline.
This is in prep for compiling with -std=c++14 and -Wno-c++17-extensions
when building with clang. Chrome has encountered problems with
third_party headers that are included both in Skia and other Chrome
sources that produce different code based on whether preprocessor macros
indicate a C++14 or C++17 compilation.

In C++17 they are already inline implicitly. When compiling with C++14
we can get linker errors unless they're explicitly inlined or defined
outside the class. With -Wno-c++17-extensions we can explicitly inline
them in the C++14 build because the warning that would be generated
about using a C++17 language extension is suppressed.

We cannot do this in public headers because we support compiling with
C++14 without suppressing the C++17 language extension warnings.

c845272b4e Broke DSLWriter into two separate classes
As DSLWriter evolved, it ended up performing two unrelated duties:

1. Holding per-thread state which is referenced throughout SkSL
   (including non-DSL code)
2. DSL-specific utility functions

There's no reason for those to be contained in the same class, and
there's also no reason the per-thread state should be held in a
DSL-specific class. This breaks out an SkSL::ThreadContext class to hold
the state info, leaving the DSL utility functions behind in DSLWriter
(which should perhaps be renamed, but that's a job for a future CL).

6d0234673a Optimize away empty for loops.
The fuzzer has found that it can get timeouts in SkVM by nesting loops
very very deeply, then at the bottom of the chain, making an inside-out
loop that runs for zero iterations. This has a calculated unrolled-size
of zero, but SkVM would still think hard about unrolling the (ultimately
empty) outer loops.

SkSL now optimizes away unrollable loops that run for zero iteratinons,
as well as empty unrollable loops. This should eliminate the fuzzer's
troublesome construct entirely.

ff5bb37b72 Replace illegal DSLTypes with Poison types.
The fuzzer has been poking various holes in DSL by intentionally
creating illegal types (e.g. private or not ES2-compatible), then
finding ways to use those types, e.g. constructors or swizzles.

Previously we were mitigating those by calling `reportIllegalTypes` at
the locations where the type was used. Now, we detect the illegal type
usage at the source, and return a poison DSLType. This prevents the
illegal type from leaking out at all, and stops the problem at its
source. It also allows us to remove calls to `reportIllegalTypes`
sprinkled through the code, as those are now redundant.

66aa1ded16 Allow precision qualifiers in function params.
Previously, `Type::applyPrecisionQualifiers` would return a new type
(e.g. `mediump + float` returned `half`) but left the precision
qualifier flags as-is. This was implemented that way because the
modifiers were already baked into a pool, so mutating them was
difficult.

The rewritten DSLParser does not share this limitation--every place
where applyPrecisionQualifiers is used, the Modifiers are easily
mutable. As a result, `applyPrecisionQualifiers` can now clear the
precision-qualifier bits on the Modifier, meaning that `half` and a
`mediump float` will generate the exact same Type/Modifier combination.

This change fixes a bug where precision qualifiers were not allowed on
function parameters. (See `check_parameters` in FunctionDeclaration.cpp
to pinpoint the cause of the error. A less-invasive fix could have just
marked those modifier bits as allowed in `check_parameters`, but this
fix addresses the root of the issue and is honestly how I wanted
`applyPrecisionQualifiers` to work all along.)
