`make check` broken on windows

[klutzy]

We only run make check-fast on windows due to slowness (#8844), but in theory it should work. It doesn't now.

My result with gcc 4.6:

failures:
    [run-pass] run-pass/glob-std.rs
    [run-pass] run-pass/linkage-visibility.rs
    [run-pass] run-pass/signal-exit-status.rs
    [run-pass] run-pass/struct-update-moves-and-copies.rs
    [run-pass] run-pass/tempfile.rs

test result: FAILED. 1314 passed; 5 failed; 54 ignored; 0 measured

gcc 4.8 result has 4 more failures due to #9205: we xfail-fasted them so they are only skipped on check-fast.

struct-update-moves-and-copies error is...

$ ./i686-pc-mingw32/test/run-pass/struct-update-moves-and-copies.stage2-i686-pc-mingw32.exe
sh: ./i686-pc-mingw32/test/run-pass/struct-update-moves-and-copies.stage2-i686-pc-mingw32.exe: Bad file number

... because UAC (at least on win 8.1 preview) saw the word "update" in filename then blocked it. :(

Others are just xfail-fasted. We could use xfail-win32 instead, but some of them may be fixable.
