Move builtin_to_string() and builtin_type() to
the CanonicalizeEntryPointIO transform. Use the former to
rename entry point IO variables to the gl_ names, and the latter
to cast values to the correct type.

More line() and less std::endl.
More automated indents and less manual spacing.
Put a single newline after every struct and function declaration.
Note that this does touch every test result, but only affects whitespace.

This transform converts all separate texture/sampler references
in a program into combined texture/samplers. This is required for GLSL,
which does not support separate texture/samplers.
As input, the transform requires a map from the unique sampler/texture
pairs previously gathered by the Resolver to strings, which will be
used as the names of the newly-generated combined samplers. Note that
binding points are unused by GLSL, and so are set to (0, 0) with
collision detection disabled.
All function signatures containing textures or samplers are rewritten,
as well as function calls and texture intrinsic calls. For texture
intrinsic calls, a placeholder sampler is used to satisfy the subsequent
Resolver pass (GLSL texture intrinsics do not require a separate sampler,
but WGSL intrinsics do). The placeholder is also used if the shader
contains only texture references (e.g., textureLoad).

Skipping those that are block-decorated is not correct, as
block-decorated structures can also have non-buffer usages. This is
even clearer now that WGSL has removed the block attribute.

Use imageSize() on images, not textureSize().
In GLSL, the LOD parameter to textureSize() is mandatory for
sampled textures, so emit a default 0 if not supplied. (Also, don't pack
the level into the coords argument; that's an HLSLism.)
GLSL returns the array size of array textures in the final component
of textureSize(); remove it for WGSL.
Write the subtype of storage images correctly (uimage*, iimage*, etc).
This required a bit of cleanup to move "writeonly" ahead of subtype
emission.

In GLSL, relational operators are only valid for scalar operands. For
vector operands, lessThan, greaterThan, etc must be used.
