We unnecessarily align data to 8 byte alignments even when -Os is
specified. This brings the logic in the AArch64 backend more in line
with the ARM backend and helps gain some image size in a few
places. Caught by an internal report on the size of rodata sections
being high with aarch64 gcc.

Conditions checked for ARM targets in vector-related effective targets
are inconsistent:
* sometimes arm*-*-* is checked
* sometimes Neon is checked
* sometimes arm_neon_ok and sometimes arm_neon is used for neon check
* sometimes check_effective_target_* is used, sometimes
* is-effective-target
This patch consolidate all of these check into using is-effective-target
arm_neon and when little endian was checked, the check is kept.

ACLE explicitly states that when targetting the common subset of
ARMv7-A, ARMv7-R and ARMv7-M, the __ARM_ARCH_PROFILE macro should not
be set. We currently set it to 'M' which is clearly erroneous.
The logic for creating this is very convoluted and also somewhat
fragile, so I've taken the opportunity to use the new CPU and
architecture definition infrastructure to record the profile for each
architecture explicitly rather than try to reconstruct it from other
data. I think this results in a much more robust solution.
