compiler: fix crash on struct that embeds pointer type
The type verification code that enforces rules about the types of
embedded struct fields was not properly handling the case where the
pointed-to type is a pointer type, e.g.
type s *struct{ C int }
type t struct{ *s }
which is illegal according to the spec. Tweak the verifier to catch
this case, and add a guard in the lowering pass to make sure that we
don't crash on invalid accesses to field "C" in type "t" above.
[BRIGFE] Improved support for function and module scope group
segment variables.
PRM specs defines function and module scope group segment variables
as an experimental feature. However, PRM test suite uses and
hcc relies on them. In addition, hcc assumes certain group variable
layout in its dynamic group segment allocation code.
We cannot have global group memory offsets if we want to
both have kernel-specific group segment size and multiple kernels
calling the same functions that use function scope group memory
variables.
Now group segment is handled by separate book keeping of module
scope and function (kernel) offsets. Each function has a "frame"
in the group segment offset to which is given as an argument.

Enable no-exec stacks for more targets using the Linux kernel.
Building glibc for many different configurations and running the
compilation parts of the testsuite runs into failures of the
elf/check-execstack test for hppa and microblaze. Those
configurations default to executable stacks in the Linux kernel
because of VM_DATA_DEFAULT_FLAGS definitions including VM_EXEC
(VM_DATA_DEFAULT_FLAGS being the default definition of
VM_STACK_DEFAULT_FLAGS).
This fails because those configurations are not generating
.note.GNU-stack sections to indicate that programs do not need an
executable stack. This patch fixes GCC to generate those sections on
those architectures (when configured for a target using the Linux
kernel), as it does on other architectures, together with adding that
section to libgcc .S sources, with the same code as used on other
architectures (or a variant using "#ifdef __linux__" instead of the
usual "#if defined(__ELF__) && defined(__linux__)" for microblaze, as
that configuration doesn't use elfos.h and so doesn't define __ELF__).
This suffices to eliminate that glibc test failure. (For hppa, the
compilation parts of the glibc testsuite still fail because of the
separate elf/check-textrel failure.)

[ARM] PR82175 - fix -mcpu=native not working correctly.
The new option processing machinery relies on %< rules in the specs to
suppress options that are rewritten. Suppression appears to be a two
phase process where the option is partially suppressed when %< is
processed and then fully suppressed at the end of the string. Strings
are separated by commas and there can be multiple strings used to form
DRIVER_SELF_SPECS.
The fix in this case is to separate the driver self specs for ARM into
separate rules as described; this forces the -m{cpu,tune,arch}=native
options to be properly removed before proceeding to the next rule set.

was very common, so the patch adds a canned definition for that,

that used a port-local FASTEST_ALIGNMENT instead of BITS_PER_WORD;
the patch uses constant_alignment_word_strings if FASTEST_ALIGNMENT
