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.

    gcc/

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

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

For hotpatching it might be required to introduce new .text parts
while keep using the existing .data/.bss sections.  To make this work
the backend needs to be prevented from using relative addressing
between code and data.

genmultilib computes combination_space, a list of all combinations of
options in MULTILIB_OPTIONS that might have multilibs built for them
(some of which may end up not having multilibs built for them, and
some of those may end up being mapped to other multilibs with
MULTILIB_REUSE).  It is then used to validate the right hand part of
MULTILIB_REUSE rules, checking with expr that combination_space
matches a basic regular expression derived from that right hand part.

There are two problems with this approach to validation:

* It requires that right hand part to have options in the same order
  as in MULTILIB_OPTIONS, in contradiction to the documentation of
  MULTILIB_REUSE saying that order does not matter there.

* combination_space can be so large that the expr call fails with an
  E2BIG error.  I have a local ARM configuration with 40 multilibs but
  3840 combinations of options from MULTILIB_OPTIONS (so 3839 listed
  in combination_space, since it doesn't list the default multilib)
  and 996 MULTILIB_REUSE rules.  This generates a combination_space
  string longer than the Linux kernel's MAX_ARG_STRLEN (PAGE_SIZE *
  32, the limit on the length of a single argv string), so that expr
  cannot be run.

This patch changes the validation approach to generate a much shorter
extended regular expression for any sequence of multilib options in
any order, and uses that for the validation instead.

Tested with a build for arm-none-eabi --with-multilib-list=aprofile
(as a configuration that uses MULTILIB_REUSE).

	Validate reuse rules against regular expression for any sequence
