cgraphunit: Don't emit asm thunks for -dx [PR106261]
When -dx option is used (didn't know we have it and no idea what is it
useful for), we just expand functions to RTL and then omit all further
RTL passes, so the normal functions aren't actually emitted into assembly,
just variables.
The following testcase ICEs, because we don't emit the methods, but do
emit thunks pointing to that and those thunks have unwind info and rely on
at least some real functions to be emitted (which is normally the case,
thunks are only emitted for locally defined functions) because otherwise
there are no CIEs, only FDEs and dwarf2out is upset about it.
The following patch fixes that by not emitting assembly thunks for -dx
either.
