2f9a98870e tint: Implement sem::Load
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.

5addefb148 Rename Constant::As to Constant::ValueAs.
This CL updates Constant::As to be Constant::ValueAs. Now that Constant
inherits from CastableBase, there is already an As method on
CastableBase. This makes the override inside Constant confusing and
potentially incorrect.

58794ae118 tint::ProgramBuilder: Simplify variable constructors
Expand the Option argument paradigm to:
* Remove the requirement to always pass a 'type' parameter. Type inferencing is the easier, and increasingly common way to declare a variable, so this prevents a whole lot of `nullptr` smell which negatively impacts readability.
* Accept attributes directly as arguments, removing the `utils::Vector{ ... }` smell.

Rename `ProgramBuilder::VarOptionals` to `VarOptions`, and add equivalent `LetOptions`, `ConstOptions` and `OverrideOptions`.

Clean up all the calls to `Var()`, `Let()`, `Const()` and `Override()`:
* Use the `Group()` and `Binding()` helpers where possible
* Removing `nullptr` type arguments
* Replace attribute vectors with the list of attributes.
* Remove already-defaulted `ast::StorageClass::kNone` arguments.
* Remove already-defaulted `ast::Access::kUndefined` arguments.

Finally, remove the `GroupAndBinding()` helper, which only existed because you needed to pass attributes as a vector.

aa037ac489 tint: Refactor sem::Constant to be less memory-hungry
Change sem::Constant to be an interface to the constant data. Implement
this so that zero-initialized data doesn't need to allocate the full
size of the type.

This also makes usage a lot cleaner (no more flattened-list of
elements!), and gives us a clear path for supporting constant
structures if/when we want to support them.

3a2a279714 Fixup various warnings in Tint which were accidentally suppressed.
When enabling the SPIR-V reader or SPIR-V writer we were suppressing
-Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables
for the `libtint` cmake target and anything that depended on that
target. Because we'd build all readers/ writers by default this caused
us to never hit those warnings.

A recent change to the cmake build sets the Tint backend based on
the Dawn backend. So, there is a much higher chance of not building
the SPIR-V support if you're on a Mac or Windows machine.

This CL removes the suppression of the warnings, adds specific pragmas
into the SPIR-V reader code which imports the SPIRV-Tools headers
and fixes up the warnings which were then firing due to checking
for the new warnings.
