<pre>Clang crashes when using vectors of half in C++ for OpenCL when the extension
is disabled.
half foo(half2 x) {
return x.s0;
}

Crash seems to happen in:
#5 0x0000562f40be7f0e clang::Sema::PerformImplicitConversion(clang::Expr*,
clang::QualType, clang::StandardConversionSequence const&,
clang::Sema::AssignmentAction, clang::Sema::CheckedConversionKind)
(/opt/compiler-explorer/clang-trunk/bin/clang+++0x4ef7f0e)
Clang doesn't crash when the extension is enabled using the expected pragma
directive.</pre>
