I looked at one of them and it is due to a nullptr mSwapChain

SwapChain11 methods.

This change adds a similar check / returning an error to

Quoting the ESSL 1.00 spec section 4.1.7: "Except for parameters to
texture lookup functions, array indexing, structure field selection,
and parentheses, samplers are not allowed to be operands in
expressions."

ESSL 3.00 has a similar passage related to opaque types.

Validate this correctly. Compatibility risk should be low, since
attempting to use samplers in ternary operators was already failing
before this in most cases.

ESSL and GLSL are not consistent on invariant matching in vertex shader
and fragment shader. See the following rules:
ESSL 1.00 - input and output must match
ESSL 3.00 - only output, inputs cannot be declared as invariant.

GLSL 1.10.59 - does not exist
GLSL 1.20.8  - input and output must match
GLSL 1.30.10 - input and output must match
GLSL 1.40.8  - input and output must match
GLSL 1.50.11 - input and output must match
GLSL 3.30.6  - input and output must match
GLSL 4.00.9  - input and output must match
GLSL 4.10.6  - input and output must match
GLSL 4.20.11 - input can omit invariant
GLSL 4.30.8  - input can omit invariant
GLSL 4.40.9  - input can omit invariant
GLSL 4.50.5  - input can omit invariant

Since GLSL 4.20, invariant qualifier description were changed to:
"
Only variables output from a shader (including those that are then input
to a subsequent shader) can be candidates for invariance. This includes
user-defined output variables and the built-in output variables. As only
outputs need be declared with invariant, an output from one shader stage
will still match an input of a subsequent stage without the input being
declared as invariant.
"
It's not very clear if input in fragment can be declared as invariant.
Mesa driver disallows use of input declared as invariant in fragment
shader, while other drivers may allow it.

In ESSL 3.00, inputs cannot be declared as invariant. ANGLE should
follow this rule for GLSL >= 4.20.

NSApplicationActivateEventType (and of course window = 0), a null
dereference happens. The crash seems timing dependent, since the root
cause was not found and this is test code, add an ugly suppression.

with several commas in the middle, it's parsed as a tree of comma
operations. It makes more sense to represent it as a binary node
rather than an aggregate node.
