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.commit 0a1ce57744f00efd14b93b8f6decb6d5eff20c66
