Ben Clayton b29396e472 fuzzers: Don't pointlessly format diagnostics
Fuzzers like to generate silly long source, and formatting large spans of these can take considerable time.
Only format the diagnostic if it is going to be displayed.

Significantly speeds up some fuzzing tests, fixing some timeouts.

Also add a minor optimization to the formatter repeat() implementation.

Corentin Wallez c6a73298c4 BUILD.gn: Directly depend on spvtools targets
Spvtools recently added support for the vkdebuginfo instructions,
causing roll failures since Tint build files didn't generate the
headers for them. Instead of adding more generator stuff in Tint's
BUILD.gn files, this commit removes everything in favor of directly
referencing spvtools' targets.

In follow-up work, the references to spvtools_internal_config will
be changed to a more narrowly scoped target so that spvtools'
warning suppressions don't get propagated to Tint.

Vasyl Teliman fa4d4341f4 Fix AST fuzzer message serialization
Currently, AST fuzzer requires that all fuzzed binaries are serialized protobuf messages.
In principle, we don't need this when we don't record mutations (which is the case right
now). Hence, this CL removes that requirement.

Vasyl Teliman 979a0b4446 Fix CLI parameters in fuzzers
This CL changes the prefix of CLI parameters in AST and SPIRV-Tools
fuzzers from `--` to `-` to make these fuzzers compatible with ClusterFuzz.
Additionally, a `tint_` prefix was added to all CLI arguments to prevent their
name collisions with LibFuzzer arguments.

Antonio Maiorano 4c9b440515 Fix FloatToString printing with not enough precision when using `fixed` floatfield format
Setting precision to `std::numeric_limits<float>::max_digits10` is valid
when using the `scientific` floatfield format when printing values.
However, we used `fixed` to make our floats more human-readable. This
change keeps the output in `fixed`, except if doing so loses precision,
in which case we fall back to `scientific`.

This fixes the rendering differences seen in the Babylon.js examples
(https://crbug.com/tint/944) between Dawn using Tint vs SPIRV-Cross, as
Tint's output was emitting values that had lost too much precision
(e.g. very small numbers being output as 0).

Ben Clayton 8a96c78931 transform: Fixes for DecomposeMemoryAccess
CloneContext::Replace(T* what, T* with) is bug-prone, as complex transforms may want to clone `what` multiple times, or not at all. In both cases, this will likely result in an ICE as either the replacement will be reachable multiple times, or not at all.

The CTS test: webgpu:shader,execution,robust_access:linear_memory:storageClass="storage";storageMode="read_write";access="read";atomic=true;baseType="i32"
Was triggering this brokenness with DecomposeMemoryAccess's use of CloneContext::Replace(T*, T*).

Switch the usage of CloneContext::Replace(T*, T*) to the new function form.

As std::function is copyable, it cannot hold a captured std::unique_ptr.
This prevented the Replace() lambdas from capturing the necessary `BufferAccess` data, as this held a `std::unique_ptr<Offset>`.
To fix this, use a `BlockAllocator` for Offsets, and use raw pointers instead.

Because the function passed to Replace() is called just before the node is cloned, insertion of new functions will occur just before the currently evaluated module-scope entity.
This allows us to remove the "insert_after" arguments to LoadFunc(), StoreFunc(), and AtomicFunc().
We can also kill the icky InsertGlobal() and TypeDeclOf() helpers.
