In the case of PREFER_SHARED_LIBGCC that probably makes sense. For
MERGE_SECTION_SEPARATOR, targetm.asm_out is fairly well developed (though
not complete), and includes both constant strings as well as functions, so
I think anything new about how assembler is output should go in there.
(Also, if having anything about how assembler is output as a hook rather
than a macro makes a measurable performance difference, either something
is very wrong about how we output assembler, or we've made extraordinary
order-of-magnitude improvements to the speed of the rest of the compiler.)
