Added support for global variables
Bug: 30964317
Pass necessary metadata about global variables--i.e., offsets of each
global variable in the synthesized global buffer--from the compiler to
the driver. This metadata is encoded as an OpString in the generated
SPIR-V code. The driver also creates the global buffer to store all
global variables.
Added support for sharing globals between invokes and kernels. rs2spirv
also does global variable access to global buffer field access
transformation for the CPU code, so that CPU and GPU access the same
global buffer resident in shared memory assuming the same data layout.
Added in the compiler support to handle global variable intializers,
and contantant expressions.
Removed capability Address, since Vulkan validation rules disallow it.
Converted OpInBoundsPtrAccessChain into OpInBoundsAccessChain, since the
former requires capability Address. OpInBoundsPtrAccessChain
instructions get generated for accesses to global variables, which are
now fields in the global buffer.
Added an RSoV test for global variables. Adjusted lit tests to check
the new OpString.
This CL is limited to non-allocation global variables, as global
rs_allocations are handled in separate CLs.
This CL does not handle constant globals either, which will be dealt
with in followup CLs.
Test: lit tests and RSoVTest

Reorganized metadata related code in rs2spirv
Bug: 30964317
Added a Context class, which is a singleton that is shared across
all LLVM and Spirit compiler passes for rs2spirv. Inside Context,
there is a bcinfo::MetadataExtractor, as well as data structures
for quick lookup of information about foreach kernels and exported
variables.
Cleaned up passes which used to use MetadataExtractor to use this
new Context.
Test: lit tests

Added methods to serialize/deserialize into/from words
Bug: 30964317
Without requirement to create input/output word streams.
Updated tests and dependent modules to use word vector as input
and output whereever applicable, instead of using word streams.
Test: unit tests, lit tests, and RSoVTest.

Added Pass and PassQueue to Spirit
Bug: 30964317
Reorganized rs2spirv using PassQueue.
Changed LiteralString from const char * to std::string, so that the
life cycle of the underneath string is correctly managed.
Improved Transformer so that it can capture changes made to the
global or decoration section while transforming function defintions.
Fixed #include order per LLVM coding convention.
Test: unit tests, lit tests, and RSoVTest

LLVM and SPIRIT transformations for global allocations
This is the initial compiler-side transformations for global allocation
support.
Added an LLVM pass to lower rsAllocationDimX calls for later SPIRIT
passes. References to alllocations in those calls are lowered into some
unique ID representing allocations of a module.
Also added a SPIRIT pass to transform lowered accessor
(rsAllocationGetDimX) in previous pass to SPIR-V load instructions from
the metadata buffer.
Generate global allocation metadata, necessary SPIR-V decorations and
declarations in the wrapper generation stage for the generated load
instrutions.
Bug: 30964317
Test: RSoV lit tests, SPIRIT unit tests

Rewrite rs2spirv using spirit
Bug: 30964317
Rewrote the wrapper generation and builtin/runtime function
translation passes in rs2spirv using spirit.
Also added support for about a dozen more floating-point builtin
math functions.
Added support for new-style root kernel with lit test. Added check
for old-style kernels with lit test. Updated existing lit tests
since generated code are slightly different, mostly on temp names.
Added SPIR-V validation to all lit tests.
Updated the RSoV driver to work with the new spirit-based compiler.
The entry point is now named entry_<kernel name>.
Fixed an issue with multi-input kernel, so that the type count is
correctly set.
Minor cleanup to destroy descriptor sets after a kernel launch
and to remove an outdated comment.
Test: lit tests and RSoVTest
