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

Fix build failures of RSoV compiler with DISABLE_NDEBUG
Uses of the DEBUG() macro in some parts of RSoV compiler triggered a
build failure with DISABLE_NDEBUG. This simple CL fixed these.

Strip non-kernel functions from RS2SPIRV compilation
Added a pass to trim out non-kernel functions from the rest of SPIR-V
compilation passes. Also changed/enforced the pass ordering so that dead
globals exposed by this pass are removed prior of SPIR-V compilation.
Bug: 30964317
Test: RSoV, RSTest, RSoV LIT tests on Angler
