594e4a1dd3 InstSimplify: Simplify trivial pointer expressions like b + (e - b)
consider:
long long *f(long long *b, long long *e) {
  return b + (e - b);
}

we would lower this to something like:
define i64* @f(i64* %b, i64* %e) {
  %1 = ptrtoint i64* %e to i64
  %2 = ptrtoint i64* %b to i64
  %3 = sub i64 %1, %2
  %4 = ashr exact i64 %3, 3
  %5 = getelementptr inbounds i64* %b, i64 %4
  ret i64* %5
}

This should fold away to just 'e'.

N.B.  This adds m_SpecificInt as a convenient way to match against a
particular 64-bit integer when using LLVM's match interface.

44b3a0b411 Declare that musttail calls in variadic functions forward the ellipsis
Summary:
There is no functionality change here except in the way we assemble and
dump musttail calls in variadic functions. There's really no need to
separate out the bits for musttail and "is forwarding varargs" on call
instructions. A musttail call by definition has to forward the ellipsis
or it would fail verification.

9d1f8b1b21 ArgPromotion: Don't touch variadic functions
Adding, removing, or changing non-pack parameters can change the ABI
classification of pack parameters. Clang and other frontends encode the
classification in the IR of the call site, but the callee side
determines it dynamically based on the number of registers consumed so
far. Changing the prototype affects the number of registers consumed
would break such code.

Dead argument elimination performs a similar task and already has a
similar check to avoid this problem.

9fe621a69e [MCJIT][SystemZ] Use a simpler expression for indirect relocation offsets.
The expressions 'Reloc.Addend - Addend' and 'Reloc.Offset' should always be
equal in this context. The latter is prefered - we want to remove the
RelocationValueRef::Addend field in the future.

c33fe1b296 Fix bug in llvm::sys::argumentsFitWithinSystemLimits().
This patch fixes a subtle bug in the UNIX implementation of
llvm::sys::argumentsFitWithinSystemLimits() regarding the misuse of a static
variable. This bug causes our cached number that stores the system command line
maximum length to be halved after each call to the function. With a sufficient
number of calls to this function, it will eventually report any given command
line string to be over system limits.

749c73842d Refactor argument serialization logic when executing process. NFC.
This patch refactors the argument serialization logic used in the Execute
function, used to launch new Windows processes. There is a critical step that
joins char** arguments into a single string, building the command line used to
launch the new process, and the readability of this code is improved if this
part is refactored in its own helper function.

8c96862847 Modernize raw_fd_ostream's constructor a bit.

big.

a4c8f31dd0 [x86] Fix a bug in r216319 where I was missing a 'break'.
This actually was caught by existing tests but those tests were disabled
with an XFAIL because of PR20736. While working on fixing that,
I noticed the test failure, and tracked it down to this.

We even have a really nice Clang warning that would have caught this but
it isn't enabled in LLVM! =[ I may look at enabling it.

ff69509f94 Remove dangling initializers in GlobalDCE
GlobalDCE deletes global vars and updates their initializers to nullptr
while leaving underlying constants to be cleaned up later by its uses.
The clean up may never happen, fix this by forcing it every time it's
safe to destroy constants.

c11cb6914d IR: remove dead code
This was added in r134994, to fix a memory leak;
three days later, r135248 switched
ContainedTys from being new-allocated to being allocated
via BumpPtrAllocator, and the earlier fix was never
reverted.

The destructor doesn't seem to ever actually be called
on Types anyway, so it's harmless, but if it were,
this'd be an invalid pointer.

This reverts r134994.

d52b1d08df TableGen: delete no-op code
This does nothing but remove the Record from the map, and
then re-add it, without actually changing it in between.

The Record's Name used to be changed before re-adding it
when the code was first committed in r137232, but the
name-changing lines were removed in r142510, and since
then this code seems to do nothing.

This was also the only caller of removeClass or removeDef,
so now RecordKeeper owns its Records unconditionally,
and could be unique_ptr-ified.
