LTO: Fix writing of toplevel asm with offloading [PR109816]
When offloading was enabled, top-level 'asm' were added to the offloading
section, confusing assemblers which did not support the syntax. Additionally,
with offloading and -flto, the top-level assembler code did not end up
in the host files.
As r14-321-g9a41d2cdbcd added top-level 'asm' to one libstdc++ header file,
the issue became more apparent, causing fails with nvptx for some
C++ testcases.
PR libstdc++/109816
gcc/ChangeLog:
* lto-cgraph.cc (output_symtab): Guard lto_output_toplevel_asms by
'!lto_stream_offload_p'.
libgomp/ChangeLog:
* testsuite/libgomp.c++/target-map-class-1.C: New test.
* testsuite/libgomp.c++/target-map-class-2.C: New test.
