[SYCL] Re-use OpenCL address space attributes for SYCL (#1581)

Fznamznon · web-flow · commit ac94b1eb537f · 2020-04-27T20:59:07.000+03:00
Today we re-use OpenCL parsed attributes, but have separate SYCL address
space semantic attributes as current implementation of OpenCL semantics
breaks valid C++. This patch enables re-use of OpenCL semantic
attributes by allowing conversions between types qualified with OpenCL
address spaces and type w/o address space qualifiers. Clang compiler
(almost) always adds address space qualifiers in OpenCL mode, so it
should not affect OpenCL mode.

NOTE: this change also disables implicit conversion between the
unqualified types and types qualified with
`__attribute__((address_space(N)))`, enabled by one of the previous SYCL
patches.
