Subject: dev-util/intel-graphics-compiler-1.0.4111: only block llvm-10 in TC

Turns out this version is not going anywhere any time soon, in fact
there is a stablereq for it now - so let's handle this properly.
Specifically, pkg_pretend() now dies if the current compiler is
clang-10+ (I think it is safe to assume that if 10 does not work nor
will the newer versions).
