In order to avoid declaring too many function parameters, we
previously modified this transform to redeclare private variables that
are only used inside a single function as function-scope
variables. This was broken as it meant that their values did not
persist across multiple calls to the same function.
Instead, wrap all private variables in a structure and pass it around
as a pointer.

... overloads for texture cube arrays
FXC is telling porkies, when it says "The array element count
of GetDimensions on TextureCubeArray objects is unavailable
on ps_5_1".
The actual issue, as identified by Teodor Tanasoaia at Mozilla,
is that the argument needs to be unsigned.
In fact, *all* the texture queries should have used an unsigned
scalar or vector for the output value. This has been broken
forever!
This reverts commit bd9f6e6684.

This change overhauls the Robustness transform to support three modes,
per address space:
* ignore - Disable robustness checks for the address space
* clamp - Clamp indices / texture args to ensure they're in
bounds. This was the old behavior, and continues to
be the default.
* predicate - Condition all indexing / textureLoad / textureStore /
atomic* operations on the bounds check. If any
dependent value is out of bounds, then the operation
is skipped.
This change also fixes multiple expression evaluation of the texture

In order to preserve padding properly for MSL, we need to use its
packed_vec type for all vec3 types in storage buffers, not just struct
members. This commit includes a complete rewrite of the PackedVec3
transform to achieve this. The key details are:
* An internal `__packed_vec3<>` type was added, which corresponds to a
`type::Vector` with an additional flag to indicate that it will be
emitted as packed vector.
* The `PackedVec3` transform replaces all vec3 types used in
host-shareable address spaces with the internal `__packed_vec3`
type. This includes vec3 types that appear as the store type of a
pointer.
* When used as an array element, these `__packed_vec3` types are
wrapped in a struct that contains a single `__packed_vec3`
member. This allows us to add an `@align()` attribute that ensures
that `array<vec3<T>>` still has the correct array element stride.
* When the `vec3<T>` appears as a struct member in the input program,
we apply the `@align()` to that member to ensure that we do not
change its offset.
* Matrix types with three rows that are used in memory are replaced
with an array of columns, where each column uses a `__packed_vec3`
inside an aligned wrapper structure as above.
* Accesses to host-shareable memory that involve any of these types
invoke a "pack" or "unpack" helper function to convert them to the
equivalent type that uses `__packed_vec3` or a regular `vec3` as
required.
* The `chromium_internal_relaxed_uniform_layout` extension is used to
avoid issues where modifying a type in the uniform address space
triggers stricter layout validation rules.

void foo(float x) {

The `int(x)` is seen as a re-declaration of `x` by DXC.
We fix this by only emitted the condition expression if it has
