Subject: [PATCH 1/4] [Driver][SYCL] Add initial SYCL offload compilation
support
Introduces the SYCL based toolchain and initial toolchain construction
when using the '-fsycl' option. This option will enable SYCL based
offloading, creating a SPIR-V based IR file packaged into the compiled
host object.
This includes early support for creating the host/device object using
the new offloading model. The device object is created using the
spir64-unknown-unknown target triple.
New/Updated Options:
-fsycl Enables SYCL offloading for host and device
-fsycl-device-only
Enables device only compilation for SYCL
-fsycl-host-only
Enables host only compilation for SYCL
RFC Reference: https://discourse.llvm.org/t/rfc-sycl-driver-enhancements/74092
