Made self.expect() errors a little more readable in the testsuite.
self.expect() had two problems:
- If there was a substrs argument, then it overwrote the variable containing
the command to run with the last substr. That meant nonsense command text in
testsuite errors.
- The actual output is not printed, which makes fixing testsuite failures a bit
annoying (you end up having to use the -tv arguments to dotest).
This fixes both of these issues. We could do even better, pretty-printing the

Support floating point values in 128-bit SSE vector registers
The System-V x86_64 ABI requires floating point values to be passed
in 128-but SSE vector registers (xmm0, ...). When printing such a
variable this currently yields an <invalid load address>.
This patch makes LLDB's DWARF expression evaluator accept 128-bit
registers as scalars. It also relaxes the check that the size of the
result of the DWARF expression be equal to the size of the variable to a
greater-than. DWARF defers to the ABI how smaller values are being placed
in a larger register.
Implementation note: I found the code in Value::SetContext() that changes
the m_value_type after the fact to be questionable. I added a sanity check
that the Value's memory buffer has indeed been written to (this is
necessary, because we may have a scalar value in a vector register), but
really I feel like this is the wrong place to be setting it.

Sema: Methods in unavailable classes are unavailable
Similar to the template cases in r262050, when a C++ method in an
unavailable struct/class calls unavailable API, don't diagnose an error.
I.e., this case was failing:
void foo() __attribute__((unavailable));
struct __attribute__((unavailable)) A {
void bar() { foo(); }
};
Since A is unavailable, A::bar is allowed to call foo. However, we were
emitting a diagnostic here. This commit checks up the context chain
from A::bar, in a manner inspired by SemaDeclAttr.cpp:isDeclUnavailable.
I expected to find other related issues but failed to trigger them:
- I wondered if DeclBase::getAvailability should check for
`TemplateDecl` instead of `FunctionTemplateDecl`, but I couldn't find
a way to trigger this. I left behind a few extra tests to make sure
we don't regress.
- I wondered if Sema::isFunctionConsideredUnavailable should be
symmetric, checking up the context chain of the callee (this commit
only checks up the context chain of the caller). However, I couldn't
think of a testcase that didn't require first referencing the
unavailable type; this, we already diagnose.

This is a follow-up to r261512, which made the 'strict' availability
attribute flag behave like 'unavailable'. However, that fix was
insufficient. The following case would (erroneously) error when the
deployment target was older than 10.9:
struct __attribute__((availability(macosx,strict,introduced=10.9))) A;
__attribute__((availability(macosx,strict,introduced=10.9))) void f(A*);
The use of A* in the argument list for f is valid here, since f and A
have the same availability.
The fix is to return AR_Unavailable from DeclBase::getAvailability
instead of AR_NotYetIntroduced. This also reverts the special handling
added in r261163, instead relying on the well-tested logic for
AR_Unavailable.

Re-apply "SelectionDAG: Store SDNode operands in an ArrayRecycler"
This re-applies r262886 with a fix for 32 bit platforms that have 8 byte
pointer alignment, effectively reverting r262892.
Original Message:
Currently some SDNode operands are malloc'd, some are stored inline in
subclasses of SDNode, and some are thrown into a BumpPtrAllocator.
This scheme is complex, inconsistent, and makes refactoring SDNodes
fairly difficult.
Instead, we can allocate all of the operands using an ArrayRecycler
that wraps a BumpPtrAllocator. This keeps the cache locality when
iterating operands, improves locality when iterating SDNodes without
looking at operands, and vastly simplifies the ownership semantics.
It also means we stop overallocating SDNodes by 2-3x and will make it
simpler to fix the rampant undefined behaviour we have in how we
mutate SDNodes from one kind to another (See llvm.org/pr26808).
This is NFC other than the changes in memory behaviour, and I ran some
LNT tests to make sure this didn't hurt compile time. Not many tests
changed: there were a couple of 1-2% regressions reported, but there
were more improvements (of up to 4%) than regressions.

P0188R1: add support for standard [[fallthrough]] attribute. This is almost
exactly the same as clang's existing [[clang::fallthrough]] attribute, which
has been updated to have the same semantics. The one significant difference
is that [[fallthrough]] is ill-formed if it's not used immediately before a
switch label (even when -Wimplicit-fallthrough is disabled). To support that,
we now build a CFG of any function that uses a '[[fallthrough]];' statement
to check.
In passing, fix some bugs with our support for statement attributes -- in
particular, diagnose their use on declarations, rather than asserting.

[tsan] Add support for pointer typed atomic stores, loads, and cmpxchg
TSan instrumentation functions for atomic stores, loads, and cmpxchg work on
integer value types. This patch adds casts before calling TSan instrumentation
functions in cases where the value is a pointer.

[x86] simplify test and tighten checks
I noticed this test as part of:

Let's show the exact codegen, so the changes will be more obvious.

[MachineInstr] Get rid of some GlobalISel ifdefs.
Now the type API is always available, but when global-isel is not
built the implementation does nothing.
Note: The implementation free of ifdefs is WIP and tracked here in PR26576.

Implement support for [[nodiscard]] in C++1z that is based off existing support for warn_unused_result, and treat it as an extension pre-C++1z. This also means extending the existing warn_unused_result attribute so that it can be placed on an enum as well as a class.

Change over the broadcaster/listener process to hold shared or weak pointers
to each other. This should remove some infrequent teardown crashes when the
listener is not the debugger's listener.
Processes now need to take a ListenerSP, not a Listener&.
This required changing over the Process plugin class constructors to take a ListenerSP, instead
of a Listener&. Other than that there should be no functional change.
