[PATCH][ARM] Fix up vectoriser dumping and scanning in some tests

[Kyrill Tkachov]

Hi all,

I noticed for some reason that these tests don't properly dump the 
vectoriser pass before scanning, but it doesn't show up because the 
corresponding target predicate in the scan-tree-dump directive was never 
true on arm!
I think these tests were initially supposed to go somewhere in the 
midend but ended up being in gcc.target/arm/.
Since they're in gcc.target/arm, just add the ARMv8 NEON options and 
expect it to always vectorise.

These tests pass on arm just fine with these changes.

Ok for trunk?

     * gcc.target/arm/vect-rounding-btruncf.c: Dump vectoriser output.
     Remove restriction on tree dump scan.
     * gcc.target/arm/vect-rounding-ceilf.c: Likewise.
     * gcc.target/arm/vect-rounding-floorf.c: Likewise.
     * gcc.target/arm/vect-rounding-roundf.c: Likewise.
