Owen Anderson 8f025f2a93 [clang] Do not emit template parameter objects as COMDATs when they have internal linkage. (#125448) ...

Per the ELF spec, section groups may only contain local symbols if those
symbols are only
referenced from within the section group. [1] In the case of template
parameter objects,
they can be referenced from outside the group when the type of the
object was declared
in an anonymous namespace. In that case, we can't place the object in a
COMDAT. This matches
GCC's linkage behavior on the test input.
