Version 3.0.0

Upgrade guidance:

The mux spec has been bumped:
- 0.74.0: to account for changes to BaseModule.
- 0.75.0: to remove code supporting cl_codeplay_program_snapshot.
- 0.76.0: to add code supporting cl_intel_required_subgroup_size.
The cl_codeplay_program_snapshot extension has been removed.
cl::binary::ProgramInfo and cl::binary::KernelInfo have been removed and
replaced with equivalent structures in the compiler namespace.
compiler::Module::finalize no longer takes a callback to populate program
info - it now takes compiler::ProgramInfo by pointer and populates it
itself if passed a non-null address.

Feature additions:

muxc now supports OpenCL C inputs, before running a (now optional) pass
pipeline. A device is required for this to work.The file type is worked out
from the file extension, and LLVM IR is assumed otherwise. Options can be
provided to this step with -cl-options. This also provides the ability to
select a device based on its index from 0, using --device-idx <idx>.
The cl_intel_required_subgroup_size OpenCL extension is now supported. Note
that no in-tree targets currently report any supported sub-group sizes so no
kernels compiled with a required sub-group size will successfully compile.
The SPIR-V SubgroupSize execution mode is now supported via the
SubgroupDispatch capability. Note that other aspects of this capability are
not supported.
The SPIR-V OptNoneINTEL capability is now supported.
compiler::BaseModulePassMachinery can now be given compiler options to
guide its decisions.
A new method - compiler::BaseModulePassMachinery::handlePipelineElement -
has been added to allow more customizable target-specific pipeline component

Future feature dropping for next major release (4.0.0):
