The previous change caused varDeclarations() to sometimes return an
expression-statement. This only made sense in the context of being
called from Parser::statement(). Other places which called
varDeclarations() expect vardecls and nothing else.

Added asserts that verify we don't try to emit the same struct or array
with two different memory layout rules. Some code paths were failing to
inspect the associated variable, leading to incorrect errors about the
attached offsets of members.
Added a test case that triggered that error, and also triggers the new
asserts.
Then, fixed the underlying cause: writing out the struct definition as a
side effect of accessing a member in getLValue().

Additionally, tests which cannot compile as RuntimeEffects (due to

and an ES3 part.

other than at global scope; the keywords are not accepted inside a

either built-in (available everywhere by design) or are clonable.

The inliner discovered that when a binary expression is inlined, its
type is not cloned into the destination's SymbolTable. This meant that
when the inlined-from function was later dead-stripped, the type pointer
would become dangling. Did a quick pass over inlineExpression and
inlineStatement and ensured that types are always copied.
Also found that `copy_if_needed` was making a copy of eligible types
each time one was encountered, instead of making one copy and reusing
it. This is fixed as well.

Unsized arrays are now allowed in exactly one place: On the declaration
of an interface block. This satisfies the one existing use-case, which
is the gl_in (sk_in) declaration for geometry shaders. There is no other
useful scenario, and most of our backends don't support them anyway.
Several spots were using less strict checks when attaching sizes to
arrays, allowing for zero or negative-sized arrays, so those are all
fixed now.
The existing tests that initialize arrays are still a problem, because
Metal doesn't support that (neither does GLES2). Also, ArrayConstructors
has gone from generating an error in the Vulkan backend, to invalid
SPIR-V.

I started unpacking the mechanics of type coercion, and realized that
the second half of the function was looking up the Symbol for a Type
based on its name (Types are already Symbols), converting that Symbol
back into a Type (we started with a Type anyway), wrapping that Type
in a TypeReference, then calling that TypeReference (which always
calls convertConstructor).
This CL cuts out the middle steps and simply calls convertConstructor
directly. A test was added to confirm that an earlier error encountered
on the CQ is no longer occurring.
