arm: Auto-vectorization for MVE: vabs
This patch adds support for auto-vectorization of absolute value
computation using vabs.
We use a similar pattern to what is used in neon.md and extend the
existing neg<mode>2 expander to match both 'neg' and 'abs'. This
implies renaming the existing abs<mode>2 define_insn in neon.md to
avoid a clash with the new expander with the same name.

* config/arm/mve.md (mve_vabsq_f<mode>): Use 'abs' instead of unspec.
(mve_vabsq_s<mode>): Likewise.
* config/arm/neon.md (abs<mode>2): Rename to neon_abs<mode>2.
* config/arm/unspecs.md (VABSQ_F, VABSQ_S): Delete.
* config/arm/vec-common.md (neg<mode>2): Rename to
<absneg_str><mode>2.
