Mahesh Ravishankar a78bd84cf8 NFC: Refactor Dialect Conversion targeting SPIR-V.
Refactoring the conversion from StandardOps/GPU dialect to SPIR-V
dialect:
1) Move the SPIRVTypeConversion and SPIRVOpLowering class into SPIR-V
   dialect.
2) Add header files that expose functions to add patterns for the
   dialects to SPIR-V lowering, as well as a pass that does the
   dialect to SPIR-V lowering.
3) Make SPIRVOpLowering derive from OpLowering class.
