Improve Cortex-A53 shift bypass
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.

Use ucontext_t not struct ucontext in linux-unwind.h files.
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.

Fix genmultilib reuse rule checks for large sets of option combinations.
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).
* genmultilib (combination_space): Remove variable.
Validate reuse rules against regular expression for any sequence
of multilib options in any order.

runtime: complete defer handling in CgocallBackDone
When C code calls a Go function, it actually calls a function
generated by cgo. That function is written in Go, and, among other
things, it calls the real Go function like this:
CgocallBack()
defer CgocallBackDone()
RealGoFunction()
The deferred CgocallBackDone function enters syscall mode as we return
to C. Typically the C function will then eventually return to Go.
However, in the case where the C function is running on a thread
created in C, it will not return to Go. For that case we will have
allocated an m struct, with an associated g struct, for the duration
of the Go code, and when the Go is complete we will return the m and g
to a free list.
That all works, but we are running in a deferred function, which means
that we have been invoked by deferreturn, and deferreturn expects to
do a bit of cleanup to record that the defer has been completed. Doing
that cleanup while using an m and g that have already been returned to
the free list is clearly a bad idea. It was kind of working because
deferreturn was holding the g pointer in a local variable, but there
were races with some other thread picking up and using the newly freed g.
It was also kind of working because of a special check in freedefer;
that check is no longer necessary.
This patch changes the special case of releasing the m and g to do the
defer cleanup in CgocallBackDone itself.
This patch also checks for the special case of a panic through
CgocallBackDone. In that special case, we don't want to release the m
and g. Since we are returning to C code that was not called by Go
code, we know that the panic is not going to be caught and we are
going to exit the program. So for that special case we keep the m and
g structs so that the rest of the panic code can use them.

compiler: add go:notinheap magic comment
Implement go:notinheap as the gc compiler does. A type marked as
go:notinheap may not live in the heap, and does not require a write
barrier. Struct and array types that incorporate notinheap types are
themselves notinheap. Allocating a value of a notinheap type on the
heap is an error.
This is not just an optimization. There is code where a write barrier
may not occur that was getting a write barrier with gccgo but not gc,
because the types in question were notinheap. The case I found was
