885c1d3048 Removed Position::Capture
It was decided that being able to report positions from C++ code is not
worth the cost of having all of these captures everywhere.

aab019a15e [bazel] Fix build

IWYU noticed one issue with DSLCore.h, which was fixed here.

08ece0c9a0 [includes] Enforce IWYU on sksl code
PS1 regenerates the Bazel files. Use it as the base change when
    comparing patchsets.

IWYU seems to do a good job of working with MyFile.cpp and
MyFile.h, but if there is just a MyHeader.h, it doesn't always
seem to throw errors if the includes aren't correct. This was
observed with include/sksl/DSL.h This might be due to the fact
that headers are not compiled on their own, so they are never
sent directly to the IWYU binary.

This change sets enforce_iwyu_on_package() on the all sksl
packages and then fixes the includes until all those checks
are happy. There were a few files that needed fixes outside
of the sksl folder. Examples include:
 - src/gpu/effects/GrConvexPolyEffect.cpp
 - tests/SkSLDSLTest.cpp

To really enforce this, we need to add a CI/CQ job that runs
bazel build //example:hello_world_gl --config=clang \
  --sandbox_base=/dev/shm --features skia_enforce_iwyu

If that failed, a dev could make the changes described in
the logs and/or run the command locally to see those
prescribed fixes.

I had to add several entries to toolchain/IWYU_mapping.imp
in order to fix some private includes and other atypical
choices. I tried adding a rule there to allow inclusion of
SkTypes.h to make sure defines like SK_SUPPORT_GPU, but
could not get it to work for all cases, so I deferred to
using the IWYU pragma: keep (e.g. SkSLPipelineStageCodeGenerator.h)

ffeb6f2339 Remove SkSL::String class.
The previous CLs have removed the last significant differences between
SkSL::String and std::string. This CL removes SkSL::String entirely and
replaces it with std::string throughout the code.

Apologies for the very long CL, but I have done my best to make it as
simple and reviewable as possible. The vast majority of changes are
simple replacement of `SkSL::String` with `std::string`. In the rare
spots where code is moved from one place to another, it is logically
unchanged.

This CL undoes most of the changes from http://review.skia.org/451739
and http://review.skia.org/451741 as these changes opened up a threading
can of worms that is probably not solvable. I no longer have a use case

1a117d7642 Allow dsl::Start with a Context instead of a Compiler.
This should allow lightweight DSL usage without needing access to a
Compiler, but some operations won't work (for now) because they rely on
the IRGenerator. Ideally, as we will reduce our dependence on
IRGenerator, these limitations will fade away.

4a5e22a8c8 Further unified error handling between SkSL and DSL
This eliminates the SkSL ErrorReporter class and funnels everything
through the DSL ErrorHandler. Since the DSL error handler can be
changed, this required a number of updates to ensure that things work
properly in the face of custom error handlers. There is probably more
work to be done in that area, but this at least passes all existing
tests.

a2d22b2e08 Broke DSLVar into separate subclasses
Previously, DSLVar represented local, global, and parameter variables.
This splits it into three separate subclasses.

In addition to just being a cleaner API in general, this also addresses
an issue we ran into with the upcoming DSLParser: previously, a global
DSLVar's storage was not set correctly until DeclareGlobal was called,
so an AddToSymbolTable call prior to DeclareGlobal would create the
SkSL variable with the wrong storage, causing spurious errors on
global-only modifiers. But holding off on the AddToSymbolTable tends to
break constructs like "int x = 0, y = x", so improving the API seemed
like the best way to address it.

Now that we have greater type safety around variables, we can
potentially avoid having to call AddToSymbolTable for DSLVar and
DSLGlobalVar altogether, since we know they are both supposed to end up
in the symbol table, but that isn't something I want to change in this
CL.

55a63afc5f Make it possible to use the DSL from within the compiler itself
The DSL would not previously function within the compiler, because it
expected to be in charge of everything itself. The compiler and DSL also
disagreed about how to handle some things, such as the DSL not
respecting the compiler's override flags.

This CL moves responsibility for much of the setup process into
DSL::Start(), which the compiler now invokes. DSL::Start() now also
takes a ProgramSettings instead of DSL-specific flags, and the
externalFunctions vector has been moved into ProgramSettings.

e9c2c5a4c3 Added support for DSL global variables
This adds an explicit DeclareGlobal call, which must now be called for
variables that were previously implicitly global.

bf3e9e9591 Remove sample-with-matrix from SkSL
This is completely unused - GrMatrixEffect is the only thing that deals
with matrix transforms on child sampling. Removing this makes everything
simpler to reason about.

debcbbf6a8 Flip the arguments to sample() when passing both coords and a color
A subset of these signatures will be available to public SkSL, and
structured in a way that really pushes the coords as the primary
argument (and color as an optional one). In any case, I find this
ordering more natural.

fe5d6928d0 DSL var values are now specified at construction time rather than in
Declare

This solves several issues caused by the lack of ordering guarantees in
C++; it was possible for the SkSL backend to look for the value of a
variable before its Declare() call gets processed. Moving the initial
value out of Declare should fix this whole class of problems.

daed2592bb Made SkSL DSL into public API
In addition to the unsurprising changes to eliminate references to
src/, we also had to tighten up some C++17-isms as they are not
permitted in public headers.
