Two of the tests are now (correctly) detected as invalid code, but were
previously checked into /shared/ because they compiled when the fuzzer
first reported them (that is, after the crash was fixed). These have
been moved into the /errors/ test folder.
One of the tests was only generating an error because its main function
was named `a` instead of `main`, so I renamed it to `main`.

DSLVar is normally implicitly converted to DSLExpression wherever it is
used, but the naively template-ized nature of DSLFunction::operator()
meant that it was accepting DSLVar parameters directly. Since DSLVar is
non-copyable, this meant DSLVar couldn't be passed directly to a DSL
function.
The smarter templates in this change are able to pass DSLVar by
reference.

This shook out a long-standing bug; constant folding would treat a
matrix resize as if the cells not covered by the original matrix were
all zero. This is wrong; GLSL populates the unknown cells with an

were updated to match the correct behavior, and an equivalent test was
added that does not constant-fold (to verify that our constant folder
matches reality).

Making a VectorCast from a compile-time constant will perform the cast
at compile-time instead; previously, we did not apply this optimization.
This simplified a few test outputs in subtle ways. (In particular, the
SPIR-V codegen used to occasionally decorate OpConstantComposite of
constant numbers with RelaxedPrecision, and no longer appears to do
this. This should have no effect on results either way AFAICS.)
Because we don't return VectorCast constructors containing compile-time
constant values, we do not need to implement compareConstant for this
constructor; they only wrap non-compile-time-constant expressions.

Similar to existing SurfaceContextReadPixels but for writes. Tries all
combinations of src/dst color type and alpha type for write pixels.
Always reads back pixels for verification using the ImageInfo of the
tested surface context.

As soon as a single VarDeclaration is successfully created, its Variable
is added to the current symbol table. However, if a variable-declaration
line declared several variables in a row, we would stop if ANY of the
declarations contained an error and discard the entire statement, but
would continue processing the rest of the program. This left us in a
position where some Variables existed in the SymbolTable with valid,
reachable names, but their corresponding VarDeclaration statement had
been thrown away as erroneous. Since Variables point back to
VarDeclarations for their initialValues, this gave us a stale pointer.
Any future reference to that variable name which could trigger an
access to its initialValue would read from this dead pointer.
This CL fixes the conversion of VarDeclarations so that we no longer
throw away any VarDeclarations associated with a successfully-parsed
Variable.

This is particularly relevant for "vector / scalar" divides, as these
end up generating an extra OpFDiv to take the reciprocal of the scalar.
This meant we were generating code to calculate "literal 1 / literal N"
at runtime whenever dividing vector V against scalar N. This fix moves
the reciprocal calculation to compile-time. And of course, it's a valid
strength reduction in all cases.
