Sanitizer instrumentation generally needs to be marked with !nosanitize,
but we're not doing this properly for ubsan's overflow checks.

r213291 has more information about why this is needed.

This change is required because the notion of count is different for
sample profiling and getProfileCount will need to determine the
underlying profile type.

This improves our behavior in a few ways:

 * We now guarantee that if a member is marked as being a member
   specialization, there will actually be a member specialization declaration
   somewhere on its redeclaration chain. This fixes a crash in modules builds
   where we would try to check that there was a visible declaration of the
   member specialization and be surprised to not find any declaration of it at
   all.

 * We don't set the source location of the in-class declaration of the member
   specialization to the out-of-line declaration's location until we have
   actually finished merging them. This fixes some very silly looking
   diagnostics, where we'd point a "previous declaration is here" note at the
   same declaration we're complaining about. Ideally we wouldn't mess with the
   prior declaration's location at all, but too much code assumes that the
   first declaration of an entity is a reasonable thing to use as an indication
   of where it was declared, and that's not really true for a member
   specialization unless we fake it like this.

This feature is subtly broken when the linker is gold 2.26 or
earlier. See the following bug for details:
  https://sourceware.org/bugzilla/show_bug.cgi?id=19002

Since the decision needs to be made at compilation time, we can not
test the linker version. The flag is off by default on ELF targets,
and on otherwise.

frames.

RuntimeDyld was previously responsible for tracking allocated EH frames, but it
makes more sense to have the RuntimeDyld::MemoryManager track them (since the
frames are allocated through the memory manager, and written to memory owned by
the memory manager). This patch moves the frame tracking into
RTDyldMemoryManager, and changes the deregisterFrames method on
RuntimeDyld::MemoryManager from:

void deregisterEHFrames(uint8_t *Addr, uint64_t LoadAddr, size_t Size);

to:

void deregisterEHFrames();

Separating this responsibility will allow ORC to continue to throw the
RuntimeDyld instances away post-link (saving a few dozen bytes per lazy
function) while properly deregistering frames when modules are unloaded.

This patch also updates ORC to call deregisterEHFrames when modules are
unloaded. This fixes a bug where an exception that tears down the JIT can then
unwind through dangling EH frames that have been deallocated but not
deregistered, resulting in UB.

For people using SectionMemoryManager this should be pretty much a no-op. For
people with custom allocators that override registerEHFrames/deregisterEHFrames,
you will now be responsible for tracking allocated EH frames.

Summary:
This fixes the immediate crash caused by introducing an incorrect inttoptr
before attempting the conversion. There may still be a legality
check missing somewhere earlier for non-integral pointers, but this change
seems necessary in any case.

The AArch64 instruction set has a few "widening" instructions (e.g., uaddl,
saddl, uaddw, etc.) that take one or more doubleword operands and produce
quadword results. The operands are automatically sign- or zero-extended as
appropriate. However, in LLVM IR, these extends are explicit. This patch
updates TTI to consider these widening instructions as single operations whose
cost is attached to the arithmetic instruction. It marks extends that are part
of a widening operation "free" and applies a sub-target specified overhead
(zero by default) to the arithmetic instructions.

The motivation for getting rid of dyn_castNotVal is to allow fixing:
https://bugs.llvm.org/show_bug.cgi?id=32706

So this was supposed to be functional-change-intended for the case
of inverting constants and applying DeMorgan. However, I can't find 
any cases where that pattern will actually get to matchDeMorgansLaws()
because we have other folds in visitAnd/visitOr that do the same
thing. So this ends up just being a clean-up patch with slight efficiency
improvement, but no-functional-change-intended.

Because IIFEs[1] are often used like an anonymous namespace around large
sections of JavaScript code, it's useful not to indent to them (which
effectively reduces the column limit by the indent amount needlessly).

It's also common for developers to wrap these around entire files or
libraries. When adopting clang-format, changing the indent entire file
can reduce the usefulness of the blame annotations.

As recently discussed on llvm-dev [1], this patch makes it illegal for
two Functions to point to the same DISubprogram and updates
FunctionCloner to also clone the debug info of a function to conform
to the new requirement. To simplify the implementation it also factors
out the creation of inlineAt locations from the Inliner into a
general-purpose utility in DILocation.
