This is the first step in being able to read code generated
by Clspv.
Actively ignore the instructions instead of applying stripping
transform before hand. That way we have a chance at properly counting
instructions, which helps produce better diagnostics.

In C++ argument evaluation order is undefined. MSVC and Clang evaluate these in different orders, leading to hilarity when writing tests that expect a deterministic ordering.
Pull out all the argument expressions to create() in the clone functions so a cloned program is deterministic in its ordering between compilers.

This is a reland of fb0bf70459c44b31419400598b592eaaae85f932
Reland after making libx11-xcb dynamically loaded since it isn't present
on all Linux deployment targets of Chromium. Also includes a couple of
additional cosmetic changes to d3d12/PlatformFunctions noticed while
looking at it for inspiration.
Original change's description:

This fixes issues where the reording might generate an invalid WGSL

This also unifies the implementation of Generate() and

Currently the queries availability info is only stored on the encoders
where they are written, and we need the info in the compute shader. If
resolving them from a different encoder, 0s are returned because the
queries are not written on resolving encoder.
Besides the encoders, we also need to add availability info to query
set, and use it in compute shader instead.
When resolving query set without any written, we need to reset queries
before resolveQuerySet based on the query set availability on Vulkan.
Added more end2end tests for these cases.

While traversing and resolving the AST, TypeOf() was called to look up
the semantic node for the given AST expression in order to fetch the
resolved type. However, for CallExpression semantic nodes are
constructed at the end of the AST traversal, and GetType() for these
would unexpectedly return nullptr, causing a crash.
To fix, have TypeDeterminer maintain an internal map of ast::Expression
to resolved type. Always populate this internal map whenever SetType() is
called. At the end of the AST traversal, have CreateSemanticNodes()
construct the semantic nodes for any ast::Expression nodes that do not
already have a semantic node assigned.
With this, GetType() will always return the type set with SetType().

Provides a centeralized table for all intrinsic overloads.
IntrinsicTable::Lookup() takes the intrinsic type and list of arguments, returning either the matched overload, or a sensible error message.
The validator has expectations that the TypeDeterminer resolves the return type of an intrinsic call, even when the signature doesn't match. To handle this, create semantic::Intrinsic nodes even when the overload fails to match. A significant portion of the Validator's logic for handling intrinsics can be removed (future change).
There are a number of benefits to migrating the TypeDeterminer and Validator over to the IntrinsicTable:
* There's far less intrininsic-bespoke code to maintain (no more duplicate `kIntrinsicData` tables in TypeDeterminer and Validator).
* Adding or adjusting an intrinsic overload involves adding or adjusting a single Register() line.
* Error messages give helpful suggestions for related overloads when given incorrect arguments.
* Error messages are consistent for all intrinsics.
* Error messages are far more understandable than those produced by the TypeDeterminer.
* Further improvements on the error messages produced by the IntrinsicTable will benefit _all_ the intrinsics and their overloads.
* The IntrinsicTable generates correct parameter information, including whether parameters are pointers or not.
* The IntrinsicTable will help with implementing autocomplete for a language server
