Snce the *args parameter was added it's assumed to be non-null. If it is
null then the function is going off to UB land. As such, a later check
added for args being NULL is useless, and confuses coverity.

(cherry picked from commit db7bfe85ae)
This also allows tools build on clc to drop their workaround to include
it themselves. Rusticl might need it once it supports extensions which
need this file pulled in.
Later if the need to include it changes based on llvm version, we can
easily handle this in clc.
The main reason to include it only conditionally is the massively
reduction in compilation time. It also removes the mental burden from
users of clc to deal with any of this themselves.

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)
v2 (Karol): use clang::CompilerInvocation::CreateFromArgs for dladdr

Clang unconditionally adds those definitions if using a spirv LLVM target.
That's not a problem on its own, but clang's internal OpenCL header enable
a bunch of OpenCL extensions if those are set.
Lucky for us, we can simply undefine them and spare us the trouble of
finding an upstream solution to this problem :)

This prevents more use-after-free errors. Passing them around using
std::unique_ptr ensures that the LLVMContext gets destroyed but doesn't
ensure destruction order. Declaring it on the stack ensures that the
context doesn't get destroyed until right before the the function
returns which is after any other LLVM stuff is destroyed.

First, separate out the LLVM context logging to make it take a
clc_logger instead of passing in a string stream. Currently, the LLVM
context may outlive the string stream which we assign which may lead to
use-after-free errors. Second, use a separate string stream for clang
diagnosticl logging which we intentionally declare before the compiler
so the compiler can't outlive it.
