Ben Clayton 0ae939bc0c writer/spirv: Refactor builder constructor tests
... using the new ast::Builder.

Also rename the test fixture name to include the common part of the test
names, and prefix with Spv. This makes it possible to run just these
tests with `--gtest_filter=SpvBuilderConstructorTest*`

Ben Clayton 165ff1c978 ast::Builder: Make the interface more fluent
Add C++ aliases for the wgsl types `i32`, `u32` and `f32`.

Separate types out from the builder and into a `Builder::Types` class. An instance of this is now held by the `Builder::ty` field. Makes it clear when you are referencing a `ast::type` instead of a constructor method.

Rework a number of builder methods so they take the type as a template argument instead of a parameter. This more closely resembles wgsl (example: `vec2<i32>(1,2)`)

Use PascalCase for the constructor methods, but keep the wgsl-like constructors lowercase to imitate the language style.

Add `BuilderWithContext` so that `Builder` can be truely immutable, and so we can remove `set_context()`.

Ben Clayton 4bfe461646 Big cleanup now that AST nodes are raw pointers
Remove all redundant std::move()s. I've also removed calls to
std::move() in tests, even if they act as an optimization. This is for
two reasons:
(a) Performance is not important for testing, and this helps with
    readability.
(b) A whole bunch tests were relying on std::move() clearing vectors so
    they can be repopulated and used again. This is undefined behavior:

> Objects of types defined in the C++ standard library may be moved from
> (12.8). Move operations may be explicitly specified or implicitly
> generated. Unless otherwise specified, such moved-from objects shall
> be placed in a valid but unspecified state.

All of these UB cases have been fixed.

Removed all duplicate variables left over from:
  `auto* foo_ptr = foo.get()`
which became:
  `auto* foo_ptr = foo`

dan sinclair 25f883520e [spirv-writer] Remove push_preamble
The push_preamble method was dealing with multiple sections of the
SPIR-V binary layout. As we changed the way things write (like
extensions getting written later) the preamble section was ending up in
incorrect order.

This CL replaces push_preamble with push methods for each of the
sections at the start of the SPIR-V module which should fixup the
ordering issue.

dan sinclair a388d56d99 [spirv-writer] Fixup constructor with bitcast parameters.
Currently if a constructor contains constructors we consider it const.
This falls down with the new type constructor syntax if the types don't
match. In the case they don't match we no longer consider the
constructor const as we'll generate OpBitcast and OpCopyObject
instructions which we need to build the composite from.
