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.

Operand is just a tagged union of uint32_t, float and std::string.
Use std::variant for this.
Reduces memory size, and removes the need to always construct an empty string when the operand is float or int.

ScopeStack is not needed here - the resolver already provides variable scoping with the sem::Variables.
Re-purpose scope_stack_ for a stack of Scope, which now holds the type constructor -> SPIR-V ID map.
This map needs to be per-scope, to fix issues like crbug.com/tint/1520

These methods produce `let` declarations.
With creation-time expressions, we'll need to add `const` declarations.
Note that module-scope `let` declarations have been removed in the spec (for `const`). ProgramBuilder::GlobalConst() has not been renamed, although it still currently produces 'let' declarations.

Concatenating strings to use for cache keys is horribly inefficent and very error prone.
Add a UnorderedKeyWrapper helper to allow types to be used as a unordered_map and unordered_set key. Use this for the type_constructor_to_id_ map.
Produces SPIR-V with some duplicate SPIR-V instructions for constructors removed.

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`.

The OpenGL ES 3.1 spec says:
"The point size is taken from the shader built-in gl_PointSize written by the vertex shader, and clamped to the implementation-dependent point size range. If the value written to gl_PointSize is less than or equal to zero, or if no value is written, the point size is undefined."
ANGLE/D3D11 will emit a warning on this and abort processing, causing dawn_end2end tests to fail.

Before this change, we duplicated line break parsing in both
Source::File and Lexer. This change makes it so that the Lexer no longer
looks for line breaks, instead relying on Source::File for this info.
This de-duplication will also help in implementing the latest spec
changes with respect to line breaks (CRLF vs CR, etc).

The current presubmit has the filter inverted so it would only attempt
to match the filtered files. The file name also has to be converted to
`LocalPath` otherwise it's attempting to compare a python object to a

The kokoro bots are running at a different level of verbosity than
the presubmit check. This CL ups the verbosity level for presubmit
to match kokoro and suppresses any new lint warnings which are
produced by the change.
The set of always removed filter options used by PRESUBMIT are
copied into the CPPLINT.cfg main file in order for kokoro to
match the errors presented by the CQ.
