For each local variable, ssa-rewrite should remove its DebugDeclare
if and only if it is replaced by any number of DebugValues for store
and phi instructions.
For example, when we have two variables `a` whose DebugDeclare
will be replaced to DebugValues by ssa-rewrite pass and `b` whose
DebugDeclare will not be replaced, we have to remove only DebugDeclare
for `a`, not `b`.
This PR introduces TransformationAddLoopPreheader, which, given
a loop header and enough fresh ids, adds a loop preheader, updating
all the references so that this new block is the only out-of-loop
predecessor of the header, which branches unconditionally to the
header.
See the discussion in #3095.
When we copy the loop body to unroll it, we have to copy its
instructions but DebugDeclare or DebugValue used for the declaration
i.e., DebugValue with Deref must not be copied and only the first block
can contain those instructions.
* Generate ext inst table for reflection

SPIRV-Tools
* Add enum for clspv reflection extended instruction set
* count it as non-semantic
* validate clspv reflection extended instruction set
* Remove local extended inst sets
* update headers deps
* Update nbuilds to use grammars from SPIRV-Headers instead of
local duplicates
Rename the `${SPIRV_TOOLS}` target to `${SPIRV_TOOLS}-static` and alias `${SPIRV_TOOLS}` to either `${SPIRV_TOOLS}-static` or `${SPIRV_TOOLS}-shared` depending on `BUILD_SHARED_LIBS`.
Re-point all internal uses of `${SPIRV_TOOLS}` to `${SPIRV_TOOLS}-static`.
`${SPIRV_TOOLS}-static` is explicitly renamed to just `${SPIRV_TOOLS}` to ensure the name does not change from current behavior.
Build the `SPIRV-Tools-*` libraries as static, as this is what they always were.
Force the external targets `gmock` and `effcee` to be built statically. These either do not support being built as shared libraries, or require special flags.
Issue: #3482
* Avoid operand type range checks
Deprecates the SPV_OPERAND_TYPE_FIRST_* and SPV_OPERAND_TYPE_LAST_*
macros.
The "variable" and "optional" operand types are only for internal use.
Export spvOperandIsConcrete instead, as that should cover intended
external uses.
Test that each operand type is classified either as one of:
- a sentinel value
- a concrete operand type
- an optional operand type (which includes variable-expansion types)
Test that each concrete and optional non-variable operand type
has a name for use internally when generating messages.

1. Set the debug scope and line information for the new replacement
instructions.
2. Replace DebugDeclare and DebugValue if their OpVariable or value
operands are replaced by scalars. It uses 'Indexes' operand of
DebugValue. For example,
struct S { int a; int b;}
S foo; // before scalar replacement
int foo_a; // after scalar replacement
int foo_b;
DebugDeclare %dbg_foo %foo %null_expr // before
DebugValue %dbg_foo %foo_a %Deref_expr 0 // after
DebugValue %dbg_foo %foo_b %Deref_expr 1 // means Value(foo.members[1]) == Deref(%foo_b)
* spirv-val: Pipes are no longer required for OpenCL 1.2 EP
This was removed from the OpenCL SPIR-V Environment Specification via

Adds a transformation that takes a pair of instruction descriptors to
OpLoad and OpStore that have the same intermediate value and replaces
the OpStore with an equivalent OpCopyMemory.
Fixes#3353.
Right now, TransformationRecordSynonymousConstants requires the type
ids of two candidate constants to be exactly the same.
This PR adds an exception for integer constants, which can be
considered equivalent even if their signedness is different.
This applies to both integers and vector constants.
The IsApplicable method of ReplaceIdWithSynonym is also updated so
that, in the case of two integer constants which don't have the same
type, they can only be swapped in particular instructions (those
that don't take the signedness into consideration).
Fixes#3536.
This PR generalises TransformationAddAccessChain so that dynamic
indices for non-struct composites (with clamping to ensure that
accesses are in-bound) are allowed.
The transformation will add instructions to clamp any index to
a non-struct composite, regardless of whether it is a constant
or not.
Fixes#3179.
Fixes an issue with the shrinker, where the message consumer set for
the shrinker was not being passed on to the replay object that the
shrinker creates. This meant that messages generated during replay
would cause an exception to be thrown.
Adds a transformation that replaces instruction OpCopyMemory with
loading the source variable to an intermediate value and storing this
value into the target variable of the original OpCopyMemory instruction.
Fixes#3352
Adds a transformation that replaces instruction OpCopyObject with
storing into a new variable and immediately loading this variable to
|result_id| of the original OpCopyObject instruction.
Fixes#3351.
Essentially, it marks all DebugInfo instructions in functions (and their operands) as live. It treats DebugDeclare and DebugValue with Deref as loads and so marks Stores of their variables as live.
It marks each DebugGlobalVariables as live except for its variable. After closure, it rechecks if the variable is live. If not, the DebugGlobalVariable instruction's variable operand is set to DebugInfoNone, per the DebugInfo spec.
Implemented AreEquivalentConstants method to check equivalency of
constants, changing IsApplicable method of
TransformationRecordSynonymousConstants to allow recording equivalence
of composite constants; added some tests to check this.
Tests with arrays and matrices still need to be added.
Fixes#3533.
Add TransformationAddRelaxedDecoration, which adds the RelaxedPrecision decoration to ids of numeric instructions (those yielding 32-bit ints or floats) in dead blocks.
Fixes#3502
Now that WebGPU ingests WGSL instead of SPIR-V,
there is no need to be so strict about the memory model.
Allow any memory model that is already allowed by Vulkan 1.0,
either directly or via an existing.
Fixes#3529
* Make BasicBlock::reachable() only consider static reachability
* Fix reachability calculation to be independent of block order
* add tests
