63a4d65e16 Revert "Added tests for sksl clone() on our test corpus"
This reverts commit 0c9b8bae42.

Reason for revert: breaking bots, apparently due to use-after-free?
Could be a real clone bug...!

41e7df4fec Disable matrix constructor tests
Given how badly these fail (even on recent NVIDIA drivers), I'm prepared
to ignore the conformance suite on this one and just disallow this in
SkSL. For now, this disables these tests so that they don't crash for
anyone running an NV GPU.

1991780081 Update LoopFloat/LoopInt tests to reduce hoisting.
Previously, none of our `runtime` tests relied on the input coordinate
in any way, so all of the logic was hoisted above the main loop in every
test. This CL adds an artificial reliance on the input coordinate so
that we have at least some SkVM tests with real code in the main loop.
This lets us see debug trace instructions interleaved with real code.

The input coordinate is clamped against a known uniform value
(`colorGreen` always contains 0101) so that the final test output
remains consistent in practice.

Additionally, I noticed that this test was only enabled in ES3, but
it doesn't seem to have anything ES3-specific in it, so it's now
enabled across the board.

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.).

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.)

e32309d771 Update switch-fallthrough test to run in dm.
Also, removed "switch containing dead code" test. This wasn't testing
anything meaningful. (When we had full CFG analysis, we could have
eliminated some of the assignments inside the switch body, but this is
not something we do anymore.)

b8f1651f9b Add workaround for switch() containing only a default case.
The Mac Radeon GLSL driver crashes when given a switch statement that
only contains a default case and returns a value. Adding a case works
around the crash, and doesn't affect the meaning of the switch.

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.

b701fa0ac0 Add non-square MatrixCompMult support to public SkSL in ES3 mode.
We already had a test case here, but it wasn't actually in operation.
The test has been split into ES2 (square) and ES3 (non-square) halves,
returns the color like a proper runtime effect, and it's now running in
dm.

Also, Metal doesn't natively support matrixCompMult, so it injects a
helper function; I tweaked the helper so it no longer requires an extra
result variable.

143e850237 Fix Metal row/column confusion, again.
We didn't have any tests which exercised the non-square matrix case
(because such a test requires ES3), so it was silently broken. It's
now fixed. The tests exposed a DIFFERENT Quadro P400 bug which will be
fixed separately.

Compile-time optimization is not yet implemented so the generated code
contains a lot of checks which will be optimized away in a followup CL.

df84ccdb38 Disable SkSLIntrinsicPackUnorm2x16 test.
This test fails on my work laptop (Radeon 5300M) so simply disabling it
on the tree isn't sufficient in this case. We don't seem to have a test
opt-out mechanism that automatically applies to local runs of dm.

14c3175d7a Add ES3 intrinsic modf to sksl_public.
The test has been improved and now covers a variety of values. Because
this intrinsic has side-effects (an out-param), we do not support
optimizing it or treating it as a constant-expression.

The modf documentation doesn't mention anything about constant-
expression support or lack thereof. Experimentally, modf is also not
treated as a constant-expression by Apple GLSL or glslang:

733fd74c29 Improve unit testing of for-loops.
An ES2-compatible for loop supports six separate rel-ops:
   < <= > >= != ==
Each rel-op, in addition to its expected usage, is also able to
represent a loop which never terminates, as well as a loop which
terminates instantly. Since SkVM unrolls these loops, we should make
sure we do it properly. We now have unit tests for all of these cases.

f89a8122a4 Fix flaws in minus-prefix optimization.
We had a logic bug when attempting to optimize the following code:
    const vecN x = vecN(a, b, c);
    -x;

The goal was to replace `-x` with `vecN(-a, -b, -c)` but we accidentally
tried to cast the `x` VariableReference to a Constructor. We
unfortunately didn't cover this in any of our test cases, but the fuzzer
managed to synthesize it by mixing and matching elements from its new
corpus.

This affected several different constructor types: splat, diagonal-
matrix, compound and array.

31c87103c6 Fix parsing error with structs containing arrays.
Previously, a struct containing a vardecl with multiple declarations
would interpret arrays incorrectly. An array would be applied to ALL
variables in the decl after its initial appearance. That is,
`int w, x[10], y, z;` would be interpreted as
`int w, x[10], y[10], z[10];`.

This is now fixed and our test case runs as expected.
