Ilia Diachkov df8713079b [SPIRV] support capabilities and extensions
This patch supports SPIR-V capabilities and extensions. In addition,
it inserts decorations related to MIFlags and improves support of switches.
Five tests are included to demonstrate the improvement.

Aleksandr Bezzubikov fa2a7a25c9 [SPIR-V] Introduce SPIR-V global entities tracking and deduplication infra.
SPIR-V module typically contains some global entities that were not
global before made it to SPIR-V, e.g. types and constants are not usually
declared globally in LLVM. By design SPIR-V requires such stuff to be declared
once and in the module's global section. Since MIR is not able to represent
such things properly they were generated per-function, and then at the very end
of the backend's pipeline hoisted into some 'meta' function minding possible
duplicates.

New SPIRVDuplicatesTracker keeps mapping of the original LLVM entities such
as types, constant, global variables, etc to their MIR counterparts -
(MachineFunction, Register). Later SPIRVModuleAnalysis (apart from other
thing it's responsible for) performs topological sorting of the
tracker's entries to ensure proper ordering before the hoisting,
and actually performs the hoisting in a duplicates-free manner
by the tracker's nature.

Ilia Diachkov 153dee34f1 [SPIR-V](6/6) Add the module analysis pass and the simplest tests
This patch adds one SPIRV analysis pass and extends AsmPrinter. It is
essential for minimum SPIR-V output. Also it adds several simplest tests
to show that the target basically works.
