[testsuite] Fixup dg-options in {gcc,g++,gfortran}.dg/vect.exp tests

Testsuites driven by vect.exp rely on check_vect_support_and_set_flags
to set appropriate DEFAULT_VECTFLAGS for a given target (e.g., add
-mfpu=neon for arm-linux-gnueabi).  Unfortunately, these flags are
overwritten by dg-options directive, which can cause tests to fail.

Behavior of dg-options is documented in vect.exp files, but not
all developers look at the .exp file when adding a new testcase.
This caused a few dg-options directives to be used instead of
the more appropriate dg-additional-options.

This patch changes target-independent dg-options into
dg-additional-options.  This patch does not touch target-specific
dg-options and target-specific tests to avoid disturbing the gentle
balance of target-specific vectorization.

This patch also removes a couple of unneeded "dg-do run" directives
to avoid failures on compile-only targets.  Default action is, again,
set by check_vect_support_and_set_flags.

Lastly, I avoided renaming tests that use -O<n> options to O<n>-*
filename format because this support is not consistent between
gcc.dg/vect/, g++.dg/vect/, and gfortran.dg/vect/ testsuites.
It seems dg-additional-options is cleaner.

This patch does the following,
1. do not change target-specific tests, e.g., gcc.dg/vect/costmodel/riscv/*;
2. do not change { dg-options FOO { target { target-*-pattern } } };
3. do not remove { dg-do run { target { target-*-pattern } } };
4. change { dg-options FOO } to { dg-additional-options FOO };
5. remove { dg-do run } in several tests, where it is clearly not needed.
