For mingw targets, there is no way to identify the end of function using
assembly directives right now.

However, emitting an end of function marker now will let us modify
check-function-bodies in scanasm.exp, which in turn enables us to write
dg-compile tests for mingw target.

Does it mean that check-function-bodies has not been configured for
x86_64-w64-mingw32 before?

I guess yes, because I couldn't find any tests involving 
check-function-bodies for x86_64-w64-mingw32.

Thanks,

In some cases, x86_64-w64-mingw32 might be configured without using SEH and it
will not emit seh_endproc. Perhaps it makes sense to apply this pattern to
aarch64-w64-mingw32 only for now.
