  [Clang] Propagate target-features if compatible when using mlink-builtin-bitcode

Buitlins from AMD's device-libs are compiled without specifying a
target-cpu, which results in builtins without the target-features
attribute set.

Before this patch, when linking this builtins with -mlink-builtin-bitcode
the target-features were not propagated in the incoming builtins.

With this patch, the default target features are propagated
if they are compatible with the target-features in the incoming builtin.
