llvm-gcc and gcc do not emit .eh_frame with that flag, clang does.

Testcase:
$ echo 'int main(){}'|clang  -fno-asynchronous-unwind-tables  -x c - -S -o
-|grep eh_frame
clang: warning: argument unused during compilation:
'-fno-asynchronous-unwind-tables'
        .section        .eh_frame,"aw", at progbits
.Lsection_eh_frame:
.Leh_frame_common:
        .long   .Leh_frame_common_end-.Leh_frame_common_begin
.Leh_frame_common_begin:
.Leh_frame_common_end:
        .long   .Leh_frame_end1-.Leh_frame_begin1
.Leh_frame_begin1:
        .long   .
