Previously these existed in each Program, but they are unchanging for
the lifetime of the Compiler. Also, their presence in the Context will
allow the SkSL::Setting class to access them outside of the IRGenerator.
Also, removed some code which allowed the IRGenerator to support null
shader-caps; this never actually happens. (The Compiler asserts that
they are non-null; the GLSL code generator uses the caps bits without a
null check, etc.)

The 'lang' was never stored or used, so this makes no current practical
difference. The original intent was to be able to specify a language so
that it could be emitted as a 'Lang' override in the 'ActualText' when
generating a PDF. However, due to the way 'ActualText' is generally used
this would be impractical. If there is ever a desire to mark up sections
of the PDF with a specific language it would be better handled in a
different way.

Now, even if a qualifier has a default value, we will know that it
appeared in the text. We can use that to check for redundant qualifiers
(as is being done here), and in the IR generator to prevent any use of
certain qualifiers, depending on context. (eg, runtime effects, wrong
shader stage, on a parameter declaration, etc.)

At IR generation time, this CL limits our optimizations to only
@switch statements. A regular switch statement will only be optimized
during the optimization phase even if the switch-value is a known
compile-time constant. This is done to avoid upsetting our reachability
analysis.
Most of this CL is moving existing logic from SkSLCompiler into
SkSLAnalysis and SkSLSwitchStatement. Although the diffs look large, the
actual changes are very small.

This splits switch() construction into two stages.
- One version of Make takes an array of case-values and case-statement
lists, and is responsible for reporting errors if the case-values are
not unique or are improperly typed. This is what the IR generator or DSL
will start with on its first encounter with the switch statement.
- The other version of Make takes an array of already-processed
SwitchCases and can assume the invariant that they're all correctly-
typed with unique values. This is what we will have when a statement
is inlined or otherwise cloned. (We still assert this invariant, for
correctness' sake, but in release mode we assume it.)
This CL doesn't perform any optimizations at Make time yet; it does work
equivalent to how `switch` works in the IR generator today. It does
improve duplicate case-label checking slightly; duplicate case labels
are now reported, and duplicate `default:` labels are detected.
(Multiple `default` labels won't pass the parser, but they can be
constructed in DSL.)

The optimizer now properly recognizes all types of exits from a switch
statement. Break, continue and return are all potential exits and need
to be considered when determining the exit path from the switch.
Previously, dead code elimination was hiding the effects of this bug
from us, but it meant that an optimized switch had the potential to
generate lots of worthless IR nodes which then needed to be detected and
eliminated by the CFG. In particular, this affected the enum form of
blend, causing a catastrophic amount of extra work to be done.

When we detect a static switch, the optimizer finds the matching switch-
case and eliminates all the other switch-cases. It handles case
fall-through by scanning forward and looking for an unconditional break.
However, the inliner has an interesting quirk--it can replace `return`
statements inside of a switch with `continue` statements, since the body
of the inlined function has been wrapped with a for-loop to allow for
early exits. The optimizer does not recognize these continue statements
as exits from the switch (although they certainly qualify), so it
treats continues as fallen-through and keeps emitting switch-cases.
The dead-code elimination pass was actually doing us a favor here and
eliminating the excess code later. A flag was added to disable DCE in
order to reveal the problem in a test.

There are two forms. Swizzle::Make supports components XYZW only;
Swizzle::MakeWith01 also supports the 01 components, and restructures
the zeros and ones into a constructor (as IRGenerator::convertSwizzle

IR generation stage, and we know that the 01 components have been
eliminated, we can avoid the extra 01-handling logic and just call
Swizzle::Make directly. This isn't a huge deal but it means that call

Surprisingly, this error is actually caught by our parser, which
interprets the default label in a unique way. From the parser comments:
"Requiring default: to be last (in defiance of C and GLSL) was a
deliberate decision. Other parts of the compiler may rely upon this
assumption."
The comment is true--we don't check for duplicate default switch-case
labels anywhere else in the code, just here in the parser.
We rely on this, so we should have a test for it.

The IRGenerator's `convertConstructor` and `coerce` were tied at the
hip--coercion can create a constructor, and creating a constructor can
cause type-coercion. This CL migrates IRGenerator::coerce to
Type::coerceExpression, and migrates IRGenerator::convertConstructor to
Constructor::Make.
Most constructor creation should go through Constructor::Make instead of
make_unique<Constructor> for best results. There are exceptions to this
rule:
- during the Compiler's `optimize` phase, we hold raw pointers to
unique_ptrs of existing expression trees, and are manually tracking
variable usage counts, so adjusting the IR tree should be done with
extreme care. Continue to use make_unique here to avoid any "surprise
improvements."
- the Rehydrator is attempting to recreate an IR tree exactly as it used
to be and doesn't want additional optimization or fixups
There are still Constructor-related optimizations in simplifyExpression
which are not yet implemented in Constructor::Make. These are migrated
to Constructor::Make at http://review.skia.org/371482

- reports both the expected string and actual DSL output

When coercing a type, we would previously call checkValid() so we could
detect function-references and type-references, so we could get a nicer
error message.
It turns out that we can just do the "is this a type-reference/
function-reference?" check directly inside coerce() and get the same
improved error messages. Since we should be coercing all our values to
the right type, and type/function-references aren't coercible to
anything, this should catch them all. I don't expect any of these
to survive all the way to the end of IR generation.
(In case one of these types does slip through, I've left the error case
in checkValid, but I've also put in an assertion. If the fuzzer can
make that assertion fire, we are probably missing a call to coerce()
somewhere.)
This cleanup is meant to help migrate coerce() out of IRGenerator.

Adds trivial name mangling to the .stage output, so we can verify that
it's working in all places (declarations, references, etc). Also added
another global variable whose initializer is - in turn - another global.

The only color filter flag is isAlphaUnchanged(), so since alpha is
unchanged through any working format transformation, we can just return
whatever flags the child filter claims.
Add a simple test.

Includes variables with and without initializers. Note that both the
.skvm and .stage output is incorrect right now. (No declarations for
global variables in .stage, and the initializer is dropped in .skvm).

None of these are legal in GLSL ES 1.0. Added a new test that previously
compiled without error. Started out with just assignment and equality,
then realized that sequence and ternary should be blocked, too.

Simply build the skvm program and look to see if in.a.id == out.a.id.
This obviously is conservative, with false negatives possible. I
haven't done it here, but one possible improvement is to splat uniforms
so constant folding can peer through uniforms too.
Add some basic tests.

This change will allow these types to be forward-declared; C++ doesn't
allow forward declaration of types declared inside a struct. Moving
these types out of Programs resulted in a large diff.
The Settings::Value helper class has been moved inside of the
IRGenerator. In practice, it was actually just an implementation detail
of how IRGenerator looks up caps-values by name. It seems very unlikely
that this will be necessary elsewhere going forward.

The FreeType and CoreText ports would use the default value for an axis
instead of the current value for any unspecified axes. Change this so
that when cloning a typeface any unspecified axes preferentially use the
current axis value if it is known.
Also adds a test that unspecified axes are not changed when cloning.
