re PR lto/81351 (Many LTO testcases FAIL)
PR lto/81351
* debug.h (dwarf2out_do_eh_frame): Declare.
* dwarf2cfi.c (dwarf2out_do_eh_frame): New predicate.
(dwarf2out_do_frame): Use it.
(dwarf2out_do_cfi_asm): Likewise.
* dwarf2out.c (dwarf2out_frame_finish): Likewise.
(dwarf2out_assembly_start): Likewise.
(dwarf2out_begin_prologue): Fix comment.
* toplev.c (compile_file): Always call dwarf2out_frame_finish
if the target needs either debug or unwind DWARF2 info.
* lto-opts.c (lto_write_options): Do not save -fexceptions,
-fnon-call-exceptions, -ffp-contract, -fmath-errno, -fsigned-zeros,
-ftrapping-math, -ftrapv and -fwrapv.
