spirv-fuzz: Do not add too many dead blocks (#4217)
Profiling has shown that adding large numbers of dead block
transformations can be expensive because each on requires dominator
analysis information, and each one invalidates this information. There
is currently no obvious mechanism for incrementally updating the
dominator analysis. This change restricts the number of these
transformations that a single fuzzer pass will apply, to restrict this
performance bottleneck.

spirv-fuzz: Optimize transformations (#4216)
Avoids blanket invalidation of analyses in several transformations,
instead updating the def-use manager and instruction to block mapping.

spirv-fuzz: Remove AddType methods from fuzzerutil (#4204)
Types should only be added to the module by spirv-fuzz via
transformations, so this change removes the AddType methods from
fuzzerutil, which were only called once each from the appropriate
transformation.

The transformations have been adapted so that they avoid redundantly
invalidating all analyses - they now update the def-use manager and
invalidate only the type manager.

spirv-fuzz: Avoid invalidating analyses (#4176)
The performance of spirv-fuzz is sometimes poor due to analyses being
conservatively invalidated. This can lead to quadratic time algorithms
when a fuzzer pass applies O(N) transformations, and where every
transformation e.g. depends on def-use analysis and invalidates
def-use analysis (because building def-use analysis is O(N)).

This change avoids invalidating analyses for certain transformations.

spirv-fuzz: Avoid unnecessary dependency (#4165)
The fuzzer library depended on CLIMessageConsumer, due to its explicit

instead, a message consumer parameter is passed.

Generate differentiated error codes for buffer oob checking (#4144)
This allows the GPU-AV layer to differentiate between errors with
uniform buffers versus storage buffers and map these to the relevant
VUIDs.

This is a resubmit of a previously reverted commit. The revert was
done as someone erroneously attempted to build the latest validation
layers with a TOT spirv-tools. The validation layers must be built with
their known-good glslang and its known-good spirv-tools and spirv-headers.

Mark module as modified if convert-to-half removes decorations. (#4127)
* Mark module as modified if convert-to-half removes decorations.

If the convert-to-half pass does not change the body of the function,
but removes decorations, it returns that nothing changed.  This is
incorrect, and will be fixed.

Set correct scope and line info for DebugValue (#4125)
The existing spirv-opt `DebugInfoManager::AddDebugValueForDecl()` sets
the scope and line info of the new added DebugValue using the scope and
line of DebugDeclare. This is wrong because only a single DebugDeclare
must exist under a scope while we have to add DebugValue for all the
places where the variable's value is updated. Therefore, we have to set
the scope and line of DebugValue based on the places of the variable
updates.

This bug makes
https://github.com/google/amber/blob/main/tests/cases/debugger_hlsl_shadowed_vars.amber
fail. This commit fixes the bug.
