[llvm] Add DW_CC_nocall to function debug metadata when either return values or arguments are removed
Adding the `DW_CC_nocall` calling convention to the function debug metadata is needed when either the return values or the arguments of a function are removed as this helps in informing debugger that it may not be safe to call this function or try to interpret the return value.
This translates to setting `DW_AT_calling_convention` with `DW_CC_nocall` for appropriate DWARF DIEs.
The DWARF5 spec (section 3.3.1.1 Calling Convention Information) says:
If the `DW_AT_calling_convention` attribute is not present, or its value is the constant `DW_CC_normal`, then the subroutine may be safely called by obeying the `standard` calling conventions of the target architecture. If the value of the calling convention attribute is the constant `DW_CC_nocall`, the subroutine does not obey standard calling conventions, and it may not be safe for the debugger to call this subroutine.

RISCV: handle 64-bit PCREL data relocations
We would previously fail to handle 64-bit PC-relative relocations on

The original changes restricted the relocation handling to the text

It would be preferable to use `R_RISCV_n_PCREL` when available to avoid

[clang] Add tests for statement expression in initializers
The commit
683e83c5
[Clang][C++2b] P2242R3: Non-literal variables [...] in constexpr
fixed a code generation bug when using (C-extension) statement
expressions inside initializer expressions.
Before that commit a nested static initializer inside the statement
expression would not be emitted, causing it to be zero initialized.
It is a bit surprising (at least to me) that a commit implementing a new
C++ feature would fix this code generation bug. Zooming in it is the
change done in ExprConstant.cpp that helps. That changes so that
"ESR_Failed" is returned in more cases, causing the expression to not be
deemed constant. This fixes the code generation as instead the compiler
has to resort to generating a dynamic initializer.
That commit also meant that some statement expressions (in particular
the ones using static variables) that previously were accepted now are
errors due to not being constant (matching GCC behavior).
Given how a seemingly unrelated change caused this behavior to change,
it is probably a good thing to add at least some rudimentary tests for
these kind expressions.

The last test models the motivating case from issue #48013.

and that leads to eliminating both subtracts.
This works for unsigned sub too, but I left that out to keep

[NFC][Thumb] Update frame-chain codegen test to use thumbv6m
The `llvm/test/CodeGen/Thumb/frame-chain.ll`, recently added by D125094,
currently fails when expensive checks are enabled due to a tMOVr
instruction that is only valid from V6 onwards.
The use of the invalid instruction is unrelated to the contents of the
original patch, and continues to be triggered by this test if its
CodeGen changes are reverted, so this patch updates the test to use V6-M
while the issue is not resolved.

Lowering was crashing with "fatal internal error: node has not been analyzed"
if a PDT with initial component value was defined inside an internal

without the component values (which happens at the instatiation).
These expression do not need to be visited (the instantiations, if any
will be). Use the form of GetExpr that tolerates the parse tree expression
to not be analyzed into an evaluate::Expr when looking through the
symbols used in an internal procedure.
Note that the PDTs TODO will then fire (it happens after the PFT

[ARM][Thumb] Command-line option to ensure AAPCS compliant Frame Records
Currently the a AAPCS compliant frame record is not always created for

be required in some cases, there are still scenarios where applications
may want to make use of the call hierarchy made available trough it.
In order to enable the use of AAPCS compliant frame records whilst keep
backwards compatibility, this patch introduces a new command-line option
(`-mframe-chain=[none|aapcs|aapcs+leaf]`) for Aarch32 and Thumb backends.
The option allows users to explicitly select when to use it, and is also
useful to ensure the extra overhead introduced by the frame records is
only introduced when necessary, in particular for Thumb targets.

[analyzer][Casting] Support isa, cast, dyn_cast of SVals
This change specializes the LLVM RTTI mechanism for SVals.
After this change, we can use the well-known `isa`, `cast`, `dyn_cast`.
Examples:
// SVal V = ...;
// Loc MyLoc = ...;
bool IsInteresting = isa<loc::MemRegionVal, loc::GotoLabel>(MyLoc);
auto MRV = cast<loc::MemRegionVal>(MyLoc);
Optional<loc::MemRegionVal> MaybeMRV = dyn_cast<loc::MemRegionVal>(V)
The current `SVal::getAs` and `castAs` member functions are redundant at
this point, but I believe that they are still handy.
The member function version is terse and reads left-to-right, which IMO
is a great plus. However, we should probably add a variadic `isa` member
function version to have the same casting API in both cases.

[lldb] Fix TestDyldExecLinux with xml enabled
NativeProcessLinux is not able to properly read libraries-svr4 data when
running with ld.so as the "main" executable. Normally, this is not a big
problem, as it returns an error message, and lldb can fallback to manual
library loading.
Unfortunately, lldb-server also does not clear cached svr4 data on exec,
which means that it does *not* return an error when the application
execs from the "regular" to the "ld.so" mode. Instead it returns
incorrect data (it is missing the main executable) and causes
TestDyldExecLinux to fail (but only when building with xml support
enabled).
This patch makes ensures that cached process data is cleared on exec,
fixing the test. Since TestDyldExecLinux has shown to be sensitive to
the way we read library info, I fork it into two (with svr4 enabled and
disabled).

[analyzer] Add blocks and ObjC messages to the call graph.
This paves the road for constructing a better function dependency graph.
If we analyze a function before the functions it calls and inlines,
there is more opportunity for optimization.
Note, we add call edges to the called methods that correspond to
function definitions (declarations with bodies).
Consequently, we should remove this dead flag.
However, this arises a couple of burning questions.
- Should the `cc1` frontend still accept this flag - to keep
tools/users passing this flag directly to `cc1` (which is unsupported,
unadvertised) working.
- If we should remain backward compatible, how long?
- How can we get rid of deprecated and obsolete flags at some point?

[lldb] Fix TCPSocket::Connect when getaddrinfo returns multiple addrs
TCPSocket::Connect() calls SocketAddress::GetAddressInfo() and tries to
connect any of them (in a for loop).
This used to work before commit
4f6d3a376c9f("[LLDB] Fix setting of
success in Socket::Close()") https://reviews.llvm.org/D116768.
As a side effect of that commit, TCPSocket can only connect to the first
address returned by SocketAddress::GetAddressInfo().
1. If the attempt to connect to the first address fails,
TCPSocket::Connect(), calls CLOSE_SOCKET(GetNativeSocket()), which
closes the fd, but DOES NOT set m_socket to kInvalidSocketValue.
2. On the second attempt, TCPSocket::CreateSocket() calls
Socket::Close().
3. Socket::Close() proceeds, because IsValid() is true (m_socket was not
reset on step 1).
4. Socket::Close() calls ::close(m_socket), which fails
5. Since commit
4f6d3a376c9f("[LLDB] Fix setting of success in
Socket::Close()"), this is error is detected. Socket::Close() returns
an error.
6. TCPSocket::CreateSocket() therefore returns an error.
7. TCPSocket::Connect() detects the error and continues, skipping the
second (and the third, fourth...) address.
This commit fixes the problem by changing step 1: by calling
Socket::Close, instead of directly calling close(m_socket), m_socket is
also se to kInvalidSocketValue. On step 3, Socket::Close() is going to
return immediately and, on step 6, TCPSocket::CreateSocket() does not
fail.
How to reproduce this problem:
On my system, getaddrinfo() resolves "localhost" to "::1" (first) and to
"127.0.0.1" (second).
Start a gdbserver that only listens on 127.0.0.1:
```
gdbserver 127.0.0.1:2159 /bin/cat
Process /bin/cat created; pid = 2146709
Listening on port 2159
```
Start lldb and make it connect to "localhost:2159"
```
./bin/lldb
(lldb) gdb-remote localhost:2159
```
Before
4f6d3a376c9f("[LLDB] Fix setting of success in Socket::Close()"),
this used to work. After that commit, it stopped working. This commit
