spirv-fuzz: Add toggle access chain instruction transformation (#3211)
In this PR, the classes that represent the toggle access chain
instruction transformation and fuzzer pass were implemented. This
transformation toggles the instructions OpAccessChain and
OpInBoundsAccessChain between them.

Fixes #3193.

spirv-fuzz: Fuzzer pass to add equation instructions (#3202)
This introduces a new fuzzer pass to add instructions to the module
that define equations, and support in the fact manager for recording
equation facts and deducing synonym facts from equation facts.

Initially the only equations that are supported involve OpIAdd,
OpISub, OpSNegate and OpLogicalNot, but there is scope for adding
support for equations over various other operators.

Combine extinst-name and extinst-output-base into one arg. (#3200)
* Combine the extinst-name and extinst-output-base into one arg.

Some build systems such as Android blueprints require that the inputs
and outputs of generator scripts are all provided as arguments.  These
two arguments to generate_language_headers.py are combined to form the
output path in the script.  This change simply lets the user provide the
whole output path as an argument.

* Fix typo in build_defs.bzl and update Android.mk

vscode: Add missing fields to schema.Opcode (#3169)

spirvfuzz: Fix type-related bug, change undef to zero, and add assert (#3188)
This fixes a bug where the type id of a type instruction, rather than
its result id, was being used.  It also favours using zero as the
return value when replacing an OpKill or OpUnreachable with a return
instruction, and adds a check that the donor module is valid when
doing module donation.

Fixes #3187.

spirv-fuzz: Fuzzer pass that adds access chains (#3182)
This change adds a fuzzer pass that sprinkles access chain
instructions into a module at random. This allows other passes to
have a richer set of pointers available to them, in particular the
passes that add loads and stores.

spirv-fuzz: Fuzzer pass to add function calls (#3178)
Adds a fuzzer pass that inserts function calls into the module at
random. Calls from dead blocks can be arbitrary (so long as they do
not introduce recursion), while calls from other blocks can only be to
livesafe functions.

The change fixes some oversights in transformations to replace
constants with uniforms and to obfuscate constants which testing of
this fuzzer pass identified.

spirv-fuzz: Ensure that donated variables are always initialized (#3181)
This change ensures that global and local variables donated from other
modules are always initialized at their declaration in the module
being transformed.  This is to help limit issues related to undefined
behaviour that might arise due to accessing uninitialized memory.

The change also introduces some helper functions in fuzzer_util to
make it easier to find the pointee types of pointer types.

spirv-fuzz: Add fuzzer passes to add loads/stores (#3176)
This change adds fuzzer passes that sprinkle loads and stores into a
module at random, with stores restricted to occur in either dead
blocks, or to use pointers for which it is known that the pointee
value does not influence the module's overall behaviour.

The change also generalises the VariableValueIsArbitrary fact to
PointeeValueIsIrrelevant, to allow stores through access chains or
object copies of variables whose values are known to be irrelevant.

The change includes some other minor refactorings.

will be able to create variables and ids using these types.

spirv-fuzz: Disallow copying of null and undefined pointers (#3172)
If the fuzzer object-copies a pointer we would like to be able to
perform loads from the copy (and stores to it, if its value is known
not to matter).  Undefined and null pointers present a problem here,
so this change disallows copying them.

Implement constant folding for many transcendentals (#3166)
* Implement constant folding for many transcendentals

This change adds support for folding of sin/cos/tan/asin/acos/atan,
exp/log/exp2/log2, sqrt, atan2 and pow.

The mechanism allows to use any C function to implement folding in the
future; for now I limited the actual additions to the most commonly used
intrinsics in the shaders.

Unary folder had to be tweaked to work with extended instructions - for
extended instructions, constants.size() == 2 and constants[0] ==
nullptr. This adjustment is similar to the one binary folder already
performs.

Fixes #1390.

* Fix Android build

On old versions of Android NDK, we don't get std::exp2/std::log2
because of partial C++11 support.

We do get ::exp2, but not ::log2 so we need to emulate that.

spirv-fuzz: Arbitrary variable facts (#3165)
This change adds a new kind of fact to the fact manager, which records
when a variable (or pointer parameter) refers to an arbitrary value,
so that anything can be stored to it, without affecting the observable
behaviour of the module, and nothing can be guaranteed about values
loaded from it. Donated modules are the current source of such
variables, and other transformations, such as outlining, have been
adapted to propagate these facts appropriately.

spirv-fuzz: Make functions "livesafe" during donation (#3146)
This change allows the generator to (optionally and at random) make
the functions of a module "livesafe" during donation. This involves
introducing a loop limiter variable to each function and gating the
number of total loop iterations for the function using that variable.
It also involves eliminating OpKill and OpUnreachable instructions
(changing them to OpReturn/OpReturnValue), and clamping access chain
indices so that they are always in-bounds.

Add spvParseVulkanEnv (#3142)
This new API lets clients request a minimal spv_target_env value
that supports a given Vulkan and SPIR-V version, by a generic
numbering scheme (as already defined by Vulkan and SPIR-V specs).

This breaks a formal source dependency from Glslang to SPIRV-Tools.
When a new API is rolled out, such as Vulkan 1.2, Glslang currently
needs to reference a specific SPIRV-Tools enum by name.
