For terminator instructions, the value profiling instrumentation
happens in a basic block other than where the value site resides.
This CR moves the instrumentation point prior to the value site.
Mostly NFC.

This makes check failures much easier to understand.
Make it empty (but leave it in the class) for NDEBUG builds.

1) For Mach-O files the code was not printing the values in hex as is the default.
2) The values printed had leading zeros which they should not have.
3) The address for undefined symbols was printed as spaces instead of 0.
4) With the -A option with posix output for an archive did not use square
brackets around the archive member name.

Instead of waiting for the domain construction to finish we will now
bail as early as possible in case a complexity problem is encountered.
This might save compile time but more importantly it makes the "abort"
explicit. While we can always check if we invalidated the assumed
context we can simply propagate the result of the construction back.
This also removes the HasComplexCFG flag that was used for the very
same reason.

They were previously expanded to CAS loops in a custom isel expansion,
but AtomicExpandPass knows how to do that generically.
Testing is covered by the existing sparc atomics.ll testcases.

Create a common accessor, DbgInfoIntrinsic::getVariableLocation, which
doesn't care about the type of debug info intrinsic. Use this to
further unify the implementations of DbgDeclareInst::getAddress and
DbgValueInst::getValue.
Besides being a cleanup, I'm planning to use this to prepare DEBUG
output without having to branch on the concrete type.

Since we have moved to a model where functions are imported in bulk from
each source module after making summary-based importing decisions, there
is no longer a need to link metadata as a postpass, and all users have
been removed.
This essentially reverts r255909 and follow-on fixes.

Mips aligns PT_LOAD to 16 bits (0x10000). That means that the lower 16
bits are always the same, so we can, effectively, say that the
relocation is relative.

Summary:
Add check misc-dangling-handle to detect dangling references in value
handlers like std::experimental::string_view.
It provides a configuration option to specify other handle types that
should also be checked.
Right now it detects:
- Construction from temporaries.
- Assignment from temporaries.
- Return statements from temporaries or locals.
- Insertion into containers from temporaries.

The CMake EXISTS operator needs to have the variable expanded. Not expanding this was causing the if statement to always be false, which made it impossible to pass linker order files in.

Summary:
Check that any function that has the property set is free of virtual
register operands.
Also, it is actually VirtRegMap (and not the register allocators) that
acutally remove the VReg operands (except for RegAllocFast).

This addresses PR27077. For some historical reason Darwin wasn't shipping multi3 in the compiler builtin library or in the OS builtin library. This caused building ffmpeg to fail because Polly was generating calls to multi3. It is easy enough to just add the builtin.

MatchBinaryOp abstracts out the IR instructions from the operations they
represent. While this change is NFC, we will use this factoring later
to map things like `(extractvalue 0 (sadd.with.overflow X Y))` to `(add
X Y)`.

Summary:
* -fcuda-target-overloads
Previously unconditionally set to true by the driver. Necessary for
correct functioning of the compiler -- our CUDA headers wrapper won't
compile without this.
* -fcuda-disable-target-call-checks
Previously unconditionally set to true by the driver. Necessary to
compile almost any external CUDA code -- almost all libraries assume
that host+device code can call host or device functions.
* -fcuda-allow-host-calls-from-host-device
No effect when target overloading is enabled.
