Unsuffixed integer literals are currently treated as i32,
but will shortly become AbstractInteger. To keep tests behaving
identically to how they are currently, change all test literals
to using either 'i' or 'u' suffixes.

Merge SintLiteralExpression and UintLiteralExpression with
IntLiteralExpression. IntLiteralExpression has a new Suffix field which
indicates whether the literal is either a:
• 'i' suffixed integer literal
• 'u' suffixed integer literal
• no-suffix integer literal
Have the SPIR-V reader produce no-suffixed literals for i32 types, to
keep this change small. In future changes the SPIR-V reader will
produce 'i' suffixed types for these.
Have all consumers of IntLiteralExpression treat unsuffixed integers the
same as 'i'-suffixed literals. Unsuffixed will be treated as abstract in
future changes.
Removed SemHelper::TypeOf(const ast::LiteralExpression* lit).

Instead of using an `if` node that has a list of `else` statements,
make each `if` statement have a single optional `else` statement,
which may itself be an `if` statement (or just a block statement).
This better matches the WGSL grammar (now that we have removed
`elseif`), and simplifies various pieces of code that handle these
statements.

These suffixes existed because the GN build errored when there were two files sets with the same name (ast + sem).
This is no longer required as the GN build splits these into two separate targets.

In this CL the enable directive is implemented.
1. Add AST node for enable directive, assign a ExtensionKind (enum) for
each supported extension.
2. Use an unorder_set in ast::Module to record all required extensions'
kind.
3. Provide inspector methods for getting names of used extension, and
getting all used enable directives' extension names and location.
4. For different writer, the extension nodes are handled in different
ways. MSL and HLSL writers will just ignore the extension nodes, while
SPIRV and GLSL writers will emit corresponding code.
5. Implement unittests and end2end test for enable directive and
inspector, using a reserved extension name `InternalExtensionForTesting`.

Since this was the only attribute allowed on structures, we can also

This transform ensures that expressions are evaluated in the order
defined in the WGSL spec. It does this by making sure to hoist
expressions that have side-effects (calls) along with variables that may
