Add an alignment test to check that aligned alloca's really do get

This patch autogenerates arm-isa.h from new entries in arm-cpus.in.
This has the primary advantage that it makes the description file more
self-contained, but it also solves the 'array dimensioning' problem
that Tamar recently encountered. It adds two new constructs to
arm-cpus.in: features and fgroups. Fgroups are simply a way of naming
a group of feature bits so that they can be referenced together. We
follow the convention that feature bits are all lower case, while
fgroups are (predominantly) upper case. This is helpful as in some
contexts they share the same namespace. Most of the minor changes in
this patch are related to adopting this new naming convention.

* sem_ch5.adb (Analyze_Assigment): If the left-hand side is an
entity of a mutable type and the right-hand side is a conditional
expression, resolve the alternatives of the conditional using
the base type of the target entity, because the alternatives
may have distinct subtypes. This is particularly relevant if
the alternatives are aggregates.

* checks.adb (Apply_Predicate_Check): If the expression is an
aggregate that is the RHS of an assignment, apply the check to
the LHS after the assignment, rather than to the aggregate. This
is more efficient than creating a temporary for the aggregate,

dynamic "others' association.
