For logical binary expressions that can be short-circuited, if the rhs
tree contained a mix of constant and runtime expressions, we would
erroneously mark the node as runtime, although some of its children were
resolved as kNotEvaluated. This would then fail during backend
generation.
This is a fork of 115820, addressing review comments, as amaiorano is OOO this week.

This CL updates ir:Value to track the instructions which use a given
value. The instructions add their usage upon construction. This
necessitates making the values non-const in a lot of places as they get
changed by the instruction.
The `result` value is moved up to the base instruction class as it
should exist in all instructions.

Before this change, the variadic function template version of
WrapInFunction would be selected when passing a utils::VectorRef<const
ast::Statement*>, even though an overload exists for that type. The
reason is that during type deduction, the compiler will select templates
over non-templates in its overload set. The only way around this was to
avoid type-deduction by explicitly casting the argument to
utils::VectorRef<const ast::Statement*>.
This CL adds a CanWrapInStatement metafunction that evaluates to true if
the arg type is one that could be passed to
ProgramBuilder::WrapInStatement. This is used to SFINAE in the variadic
args version of WrapInFunction.

This change is a necessary to support workgroupUniformLoad in a
following patch. Otherwise, there is no change to the set of shaders
that are accepted or rejected by the analysis.
We now distinguish between uniformity requirements on the contents of
a pointer parameter versus the pointer value itself when generating
tags for function parameters.
Whilst processing an expression, if we see a sem::Load node we pass a
flag down through child expressions to indicate that we will be
loading from the result. When processing an identifier expression, we
can then select between adding an edge to the source of the
pointer/reference versus the contents of the root identifier that it
corresponds to.
Since the pointers passed to atomic builtins can be uniform, we
special-case them to capture the fact that their return value is
always considered non-uniform.
The arrayLength builtin no longer needs special-casing.
Added many tests to cover various cases that are now captured
differently in the graph. There are two cases that are disabled as
they require variable pointers to trigger the uniformity violation.

The resolver now wraps sem::Expression objects with a sem::Load object
anywhere that the load rule is invoked. sem::Expression provides an
`UnwrapLoad()` method that returns the inner expression (or
passthrough, if no load is present), which is analaguous to
Type::UnwrapRef().
The logic for alias analysis in `RegisterLoadIfNeeded` has been folded
into the new `Resolver::Load` method.
Fixed up many transforms and tests. The only difference in output is
for a single SPIR-V backend test, where some IDs have changed due to
slight re-ordering of when expressions are generated.
There may be further clean-ups possible (e.g. removing unnecessary
calls to `UnwrapRef`, and simplifying places in the SPIR-V writer or
transforms that deal with memory accesses), but these can be addressed
in future patches.
