The tool was getting slow, due to the number of branches being examined.
M96 is the latest stable release. We aren't applying fixes to this or older branches.
Also avoids an issue where the M95 branch was missing a cherry-pick, which the tool wanted to merge with each run.

This CL implements RequestDevice and also has changes for
Dawn to internally use wgpu::FeatureName enums, instead of
strings. Some of the string handling is kept for now to
support the deprecated creation path. GetFeatureInfo is added
to the instance to get a name and description of the feature,
for reporting in about://gpu.
Dawn device toggles are now passed in an extension struct off
of the device descriptor. This is only supported in dawn_native,
and not dawn_wire, for now, since dawn_wire doesn't have a way
to serialize lists of null-terminated const char*.
To enable the client to check whether the toggle descriptor is
supported, a `dawn-native` feature is added which is supported
all the time with dawn_native, but not supported with dawn_wire.
Feature `dawn-native` also enables a synchronous version of
CreateDevice for convenience.

This patch tries to use the data directly in deserialized buffer
when the data is "data-only" and doesn't affect the control flow instead
of allocating and copying into a temporary buffer. Due to the protection
of TOCTOU attacks, currently we only set "wire_is_data_only" on the
parameter "data" in Queue.WriteBuffer() and Queue.WriteTexture().
With this patch, the performance of dawn_perf_tests
BufferUploadPerf.Run/*_WriteBuffer_BufferSize_* with "-w" will
be greatly improved (~20%) when the upload buffer size is greater than
1MB.

Migrate some of the validation logic over to use the results of behavior
analysis.
The most significant changes are:
* Unreachable-statements now consider merge-points of control flow. For
example, if all branches of a if-statement or switch-statement either
return or discard, the next statement will be considered unreachable.
* Unreachable statements are no longer an error, but a warning. See
https://github.com/gpuweb/gpuweb/issues/2378.
* Statements that follow a loops that does not break, or have a
conditional will now be considered unreachable.
* Unreachable statements produced by the SPIR-V reader are now removed
using the new RemoveUnreachableStatements transform.
Some other new changes include additional validation for the continuing
block for for-loops, to match the rules of a loop continuing block.
The new cases this validation is testing for are not expressible in
WGSL, but some transforms may produce complex continuing statements that
might violate these rules. All the writers are able to decay these
complex for-loop continuing statements to regular loops.

The SwitchCaseBlockStatement was bound to the BlockStatement of an ast::CaseStatement, but we had nothing that mapped to the actual ast::CaseStatement.
sem::CaseStatement replaces sem::SwitchCaseBlockStatement, and has a Block() accessor, providing a superset of the old behavior.
With this, we can now easily validate the `fallthrough` rules directly, instead of scanning the switch case. This keeps the validation more tigtly coupled to the ast / sem nodes.
