Re: patch: cleanup gcc.dg/vect/

["Chao-ying Fu" <fu at mips dot com>]

mipsisa64*-*-* only supports V2SF mode (two single floating point in
parallel).
If tests try to vectorize integer code, these tests will fail on
mipsisa64*-*-*.
So, mipsisa64*-*-* is specified in 31 tests that vectorize the float array
only.
