5fad2b8849 Reland "Use SkSL "offset" to actually mean "line""
This reverts commit a909dd6b8d.

Turns out those reportPendingErrors() calls I removed were in fact
necessary, just not on any of the CQ bots.

b05bbd03f9 Fix for fuzzer-discovered error with invalid var-initializers.
If a VarDeclaration line contained multiple variables, and the first
variable had an illegal initializer-expression, the Declare() would
return a Nop. AddVarDeclaration did not expect to see a Nop and would
assert once we tried to process the second var-declaration. Now, we
allow adding var declarations to a Nop.

Bulked up some tests to cover local and global variables (since those
are parsed in separate functions) and to check both the first
initializer as well as follow-on initializers (since those are parsed in
separate parts of the var-decl handler).

fcc0ef1ee4 Remove all clamping to "valid" premultiplied colors
Previously, we were abundantly cautious about producing premultiplied
colors with RGB > A, when the color-type was normalized fixed-point.

I'm not seeing any evidence that code cares about that. If it does, I
suggest we fix the issue at the API border, or via dedicated pass. In
the common case, this makes Skia less opinionated, which (in general)
makes it more versatile.

a909dd6b8d Revert "Use SkSL "offset" to actually mean "line""
This reverts commit 47f76853c6.

Reason for revert: Test failures

Original change's description:
> Use SkSL "offset" to actually mean "line"
>
> SkSL internally tracks token offsets, but only ever reports errors using
> line numbers. With the introduction of the DSL, which (being embedded in
> C++ source) only has access to line numbers in the first place, tracking
> offsets went from merely providing little benefit to actively making
> life more difficult.
>
> We are changing SkSL's position tracking from handling offsets to
> handling line numbers, but to simplify the review process the change is
> split up into two main steps. The first step (this CL) starts using
> line numbers everywhere, but avoids the thousand-line churn of actually
> renaming "offset", so most "offset" fields, variables, and parameters
> will be briefly misnamed and will actually contain a line number.
>
> The followup CL will complete the process by renaming all of the
> now-misnamed fields, variables, and parameters, but will not make any
> behavioral changes.

58d47fa1ec Renamed SkSL "offset" to "line"
https://skia-review.googlesource.com/c/skia/+/451419 changed the meaning
of "offset" throughout SkSL, so that it was actually tracking line
numbers rather than offsets (and thus had a misleading name). This
completes the transition by renaming all of the now-misnamed "offset"
fields, parameters, and variables to "line'.

47f76853c6 Use SkSL "offset" to actually mean "line"
SkSL internally tracks token offsets, but only ever reports errors using
line numbers. With the introduction of the DSL, which (being embedded in
C++ source) only has access to line numbers in the first place, tracking
offsets went from merely providing little benefit to actively making
life more difficult.

We are changing SkSL's position tracking from handling offsets to
handling line numbers, but to simplify the review process the change is
split up into two main steps. The first step (this CL) starts using
line numbers everywhere, but avoids the thousand-line churn of actually
renaming "offset", so most "offset" fields, variables, and parameters
will be briefly misnamed and will actually contain a line number.

The followup CL will complete the process by renaming all of the
now-misnamed fields, variables, and parameters, but will not make any
behavioral changes.

cb40008b43 Implement switch in SkVM.
SkVM implements switches as a pseudo-loop; breaks are handled with the
condition mask just like a for loop. Fallthrough is handled via a
scratch Value in a temporary slot. `writeStore` neeeded to be refactored
to support writing into slot(s) without an associated Variable.

At IR generation time, SwitchStatements are now emitted without error
even in strict-ES2 mode. The GLSL code generator currently reports these
as an error in strict-ES2 mode, but this will be fixed in a followup
coming shortly (the switch will be rewritten as ifs inside a one-shot
loop, similar to our IR-rewrite strategy).

eb68973c2f Disallow matrix ctors which overflow a column.
The GLSL spec allows matrix constructors containing vectors that would
split between multiple columns of the matrix. However, in practice, this
does not actually work well on a lot of GPUs!

- "cast not allowed", "internal error":
	Tegra 3
	Quadro P400
	GTX 660
	GTX 960
- Compiles, but generates wrong result:
	RadeonR9M470X
	RadeonHD7770

Since this isn't a pattern we expect to see in user code, we now report
it as an error at compile time. mat2(vec4) is treated as an exceptional
case and still allowed.

2dda4b6563 Allow Mangler to be used outside of Inliner.
It now lives in the Compiler instead of the Inliner, and we have a
pointer to it inside the Context. I also took the opportunity to remove
a few unnecessary #includes from Context and fixed up the fallout from
this.

POTENTIALLY IMPORTANT FOOTNOTE: DSLWriter has its own Mangler object
inside of it. I experimented with removing this and having it share the
Mangler object inside the Context, but this caused failures in
"testThreading" and "testpersistentcache" CQ bots; the Expected and
Actual images would mismatch. (The Expected would be missing some
draws.) This particularly affected some blur-related tests which are
likely to be GaussianConvolution--i.e. it uses DSL.
This might be a canary in the coalmine for some quirky DSL threading
issue? e.g. using the same Context on two threads at once?

0dc09b190a Update SkSLTest to check a 2x2 surface.
Derivative tests don't really make intuitive sense in a 1x1 surface.
This should give the derivatives a better workout.

4f1593eaee Use swizzles in Metal matrix helper functions.
Not a big deal necessarily, but considering using this logic in GLSL as
well, and I'm less confident that your average GLSL ES driver will
optimize away the separate array loads.

a047e8bf4d Improve overflow checks in CheckProgramUnrolledSize.
The fuzzer discovered that it could overflow the program-size value.
Rewrote the logic to use SkSafeMath everywhere, and to early-exit as
soon as a statement manages to exceed the program size.
