Store the original stack pointer (on entry to the syscall dispatcher)
in syscall_frame; the stack pointer itself is incremented by
"pop {r0-r3}" right before calling the syscall itself.
This fixes unwinding from functions set up by syscalls, like
KiUserExceptionDispatcher.

We ideally should back up all of d0-d31, but when building in ELF
form, only d0-d15 are normally available (with common distributions'
default compilers), unless object files are built with flags to enable
support for d16-d31 (with e.g. -mfpu=neon).

RtlCaptureContext doesn't set context->Lr, which is needed for
being able to unwind from the context.
This matches what is done in the arm64 version.

This does the same as 23b44e8df6,
but for arm:
Don't call KiUserExceptionDispatcher directly on the stack pointer
stored in the CONTEXT, but use the one stored in syscall_frame
(which includes the stack allocation in e.g. RtlRaiseException).

This differs slightly from the official docs (which is clear in some
places, vague in others, and contradictory in some places), based
on actual observed behaviour.

This isn't mentioned in the documentation (which only writes out the
instruction that is executed while unwinding, i.e. the mirror form of
it), but a prologue version of this instruction would look like this.

Some functions aren't available in real kernel32.dll on i386, even if
they are available in ntdll (and thus are available on x86_64,arm,arm64),
some should be available on more architectures but aren't implemented
in ntdll yet.

This doesn't fix (or break) any case known to me, but the code seems
wrong.
Leaf functions on arm (either 32 or 64) don't generally have any
default/implicit stack allocation.

These signatures extend the OSG5 format by a minimum precision hint, which gets
ignored for now but could be implemented using 16-bit floats in the future.
