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.

41e4d9a34 adjusted the tab indentation from 2 to 4 whitespaces.
Apply this to the templates so that regenerating these produce no diffs.

This CL updates the clang format files to have a single shared format
between Dawn and Tint. The major changes are tabs are 4 spaces, lines
are 100 columns and namespaces are not indented.

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.

Implement new transform UnwindDiscardFunctions that replaces discard
statements with setting a module-level bool, adds a check and return for
this bool after every function call that may discard, and finally
invokes a single function that executes a discard from top-level
functions.
Regenerated tests and remove HLSL ones that used to fail FXC because it
had difficulty with discard.

Add a Hash() and Equals() methods to sem::Type.
Have sem::Manager (which should be called sem::TypeManager) derive from
utils::UniqueAllocator. This now uses the Hash() and Equals() for uniquely
constructing semantic types instead of building strings and comparing those.
