LLVM_LIB_DIR is a variable used for runtime compilations.
When cross compiling, LLVM_LIB_DIR must be set to the
libclang path on the target. So, this path should not
be retrieved during compilation but at runtime.
dladdr uses an address to search for a loaded library.
If a library is found, it returns information about it.
The path to the libclang library can therefore be
retrieved using one of its functions. This is useful
because we don't know the name of the libclang library
(libclang.so.X or libclang-cpp.so.X)

Setting opencl-external-clang-headers to enabled while using shared LLVM
was broken and this option was mostly used for windows to force static
inclusion of opencl base headers.
Simply relying on the shared-llvm option here is enough to get what we

It is broken and clang uses fp32 for float constants if the fp64 extension
isn't enabled anyway. SPIRVs can't use fp64 constants with printf unless
they enable the Float64 cap, which also requires cl_khr_fp64 to be
supported.
So just remove it and rely on clang handling -cl-single-precision-constant
correctly, which at the moment doesn't seem to be the case, but we can
think about that once we plan to support cl_khr_fp64.

When we use source from ALU instruction directly, the default swizzle array
should be populated with the same amount of components as the src has.
Otherwise, if we use nir_ssa_alu_instr_src_components, it can return
the destination components count that is lower than component index
actually used in that source. This can lead to false equality
between 0 (uninitialized) and 0 (.x) in swizzle comparison below.
