Committed: Fix test-case gcc.dg/pr18164.c

[Hans-Peter Nilsson]

Committed as obvious.  It's an implied requirement that you test
your test-cases *within the test-suite framework*.  The missing
dg-options "" caused the default option "-ansi" and GCC horked
on the asm.  The "{dg-error" missing space typo caused dejagnu
to not see the dg-error.  It's really not hard to test separate
test-cases.  In this case (and assuming native build):
 make check-gcc 'RUNTESTFLAGS=dg.exp=pr18164.c'

	* gcc.dg/pr18164.c: Add dg-options "".  Correct typo in dg-error.
