We unnecessarily align data to 8 byte alignments even when -Os is

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.

This patch fixes a failure in gcc.target/aarch64/reload-valid-spoff.c
triggered by https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01367.html.
In ILP32 all memory accesses must have Pmode as the base address, but
aarch64_expand_mov_immediate wasn't emitting a conversion in one case.
Besides fixing this add an assert that flags any MEM operands that are
not Pmode.

The aarch_forward_to_shift_is_not_shifted_reg bypass always returns true
on AArch64 shifted instructions. This causes the bypass to activate in
too many cases, resulting in slower execution on Cortex-A53 like reported
in PR79665.
This patch uses the arm_no_early_alu_shift_dep condition instead which
improves the example in PR79665 by ~7%. Given it is no longer used,
remove aarch_forward_to_shift_is_not_shifted_reg. Also remove an
unnecessary REG_P check.

Current glibc no longer gives the ucontext_t type the tag struct
ucontext, to conform with POSIX namespace rules. This requires
various linux-unwind.h files in libgcc, that were previously using
struct ucontext, to be fixed to use ucontext_t instead. This is
similar to the removal of the struct siginfo tag from siginfo_t some
years ago.
This patch changes those files to use ucontext_t instead. As the
standard name that should be unconditionally safe, so this is not
restricted to architectures supported by glibc, or conditioned on the
glibc version.
Tested compilation together with current glibc with glibc's
build-many-glibcs.py.
