This commit improves the prologue scanning stack unwinder, to better
support AUIPC, LUI, and more variants of ADD and ADDI.
This allows unwinding over frames containing large local variables,
where the frame size does not fit into a single instruction immediate,
and is first loaded into a temporary register, before being added to
the stack pointer.
A new test is added that tests this behaviour. As there's nothing
truely RiscV specific about this test I've added it into gdb.base, but
as this depends on target specific code to perform the unwind it is
possible that some targets might fail this new test.

PR python/18170 questions why it's not possible to convert a pointer

Digging a bit shows that the Python 2.7 int() constructor will happily

this in other places -- this is what gdb_py_object_from_longest
handles.
So, this patch simply extends valpy_int to allow pointer conversions,
as valpy_long does.

This causes the inferior to stop with SIGTTIN if it tries to read from the
terminal after it has been continued.
See https://cygwin.com/ml/cygwin/2016-09/msg00285.html for reproduction.
Since MinGW doesn't have a tcsetpgrp(), I don't think this problem would be
observed there, but Cygwin does so target_terminal::ours() will call it.
Calling target_terminal::ours() here seems to be is no longer appropriate
after the "Merge async and sync code paths" changes (as the inferior is now
in a separate process group even in sync mode(?), which is always used on
Windows targets)
This call was added in commit c44537cf (and see
https://sourceware.org/ml/gdb-patches/2007-02/msg00167.html for what it
fixed, which is not regressed by this change)
When windows_nat_target::wait() is entered, the inferior is running (either
it's been just been started or attached to, or windows_continue() was
called), so grabbing the controlling terminal away from it here seems to be
wrong, since infrun.c takes care of calling target_terminal::ours() when the
inferior stops.

I believe it's because uint64_t is defined as "unsigned long long" on macOS,
even though "unsigned long" is also 64 bits. Other 64-bits platforms define
uint64_t as "unsigned long".
This makes the type of the argument to store_integer (unsigned long long) not
match the requirement that it must be the same as ULONGEST, which is unsigned
long.
Fix it by changing the type of the vl variable to be ULONGEST, which is what
extract_unsigned_integer returns anyway.

This procfs.c (and friends) cleanup patch grew along a couple of lines:
* First I noticed that PR_MODEL_NATIVE is always defined now that
Solaris 10 is the minimum supported version.
* Then there was a cleanup that I'd missed when removing support for
!NEW_PROC_API, IRIX, and Tru64 UNIX: given that sysset_t is no longer
dynamic, there's no need for the special sysset_t_alloc, but we can
just use XNEW instead.
* Then I found one of those ARI warning mails on gdb-patches, discovered
how to run it myself and fixed a large number of the warnings, among
them all uses of sprintf.
I had to silence the warnings in only 3 instances of the same issue,
namely references to LDT in function names which are due to the

make[4]: *** [config/tc-arc.o] Error 1
observed with GCC 4.1.2 and presumably other C89 compilers with the
`arc-elf' and `arc-linux-gnu' targets, caused by the use of constants
the values of which are outside the range of the `int' type (or the
`long' type if it is of the same with). In the C89 language standard
such constants are not implicitly converted to a wider type and an
explicit suffix is required for such constants.
Add a `ull' suffix then as with such constants used in other ports.
gas/
* config/tc-arc.c (md_number_to_chars_midend): Append `ull' to
large constants.
opcodes/
* arc-nps400-tbl.h: Append `ull' to large constants throughout.
Remove duplicate `rs6000-*-aix5.[01]' and `rs6000-*-aix[5-9]*' target
configuration selectors meant to correspond to `powerpc64-*-aix5.[01]'
and `powerpc64-*-aix[5-9]*' respectively for the purpose of BFD target
vector selection in `config.bfd'.
These selectors were added with commit 9a9e2ca332 ("rs6000 xcoff bfd
config"), <https://sourceware.org/ml/binutils/2010-12/msg00372.html>,
and have been dead right from the beginning, because they appear twice
each in the case statement, which means the earlier instance of each
takes precedence and the other one is ignored. Here ones that alias to
`powerpc-*-aix5.[01]' and `powerpc-*-aix[5-9]*' respectively immediately
above are used instead.
bfd/
* config.bfd <rs6000-*-aix5.[01], rs6000-*-aix[5-9]*>: Remove
duplicate `case' selectors.
We have not only removed all unsupported and obsolete code, but also supported lost of new features,
including better link-time relaxations and TLS implementations. Besides, the files generated by the
newly assembler and linker usually get higher performance and more optimized code size.
