Hans Wennborg c980408c71 Fix failing test/Sema/wchar.c on ARM.
Currently Sema/wchar.c fails because WCHAR_T_TYPE is defined as int,
however on ARM wchar_t is unsigned int.

This patch changes that, so this test passes for ARM.

John McCall 82fb892019 When performing a ::delete of an object with a virtual destructor,
be sure to delete the complete object pointer, not the original
pointer.  This is necessary if the base being deleted is at a
non-zero offset in the complete object.  This is only required
for objects with virtual destructors because deleting an object
via a base-class subobject when the base does not have a virtual
destructor is undefined behavior.

Noticed while reviewing the last four years of cxx-abi-dev
activity.

Chandler Carruth 8b907e8acb Fix a case where SROA did not correctly detect dead PHI or selects due
to chains or cycles between PHIs and/or selects. Also add a couple of
really nice test cases reduced from Kostya's reports in PR13905 and
PR13906. Both are fixed by this patch.

Duncan Sands 3f4d0b1724 Change the way the lint sanity checking pass detects misaligned memory accesses.
Previously it was only be able to detect problems if the pointer was a numerical
value (eg inttoptr i32 1 to i32*), but not if it was an alloca or globa.  The
reason was the use of ComputeMaskedBits: imagine you have "alloca i8, align 2",
and ask ComputeMaskedBits what it knows about the bits of the alloca pointer.
It can tell you that the bottom bit is known zero (due to align 2) but it can't
tell you that bit 1 is known one.  That's because the address could be an even
multiple of 2 rather than an odd multiple, eg it might be a multiple of 4.  Thus
trying to use KnownOne is ineffective in the case of an alloca as it will never
have any bits set.  Instead look explicitly for constant offsets from allocas
and globals.

John McCall b0433eeb2e During jump-scope checking, build an ExprWithCleanups immediately
into the enclosing scope;  this is a more accurate model but is
(I believe) unnecessary in my test case due to other flaws.
However, one of those flaws is now intentional:  blocks which
appear in return statements can be trivially observed to not
extend in lifetime past the return, and so we can allow a jump
past them.  Do the necessary magic in IR-generation to make
this work.

Richard Smith 88d67f3412 Fix crash when a decltype expression in a trailing return type refers to the
function being instantiated. An error recovery codepath was recursively
performing name lookup (and triggering an unbounded stack of template
instantiations which blew out the stack before hitting the depth limit).

Chandler Carruth 2603a18769 Fix a crash in SROA. This was reported independently by Takumi and
David (I think), but I would appreciate folks verifying that this fixes
the big crasher.

I'm still working on a reduced test case, but because this was causing
problems I wanted to get the fix checked in quickly.

I also moved the SDKROOT setting into the make flags, since clearing it from

line.  That hasn't been a problem but it could be, and it's good to be
consistent with the way UNIVERSAL_SDK_PATH is handled.

always build against LLVM/Clang top-of-tree, and
that problems building will be resolved as they
occur.  Stable release branches of LLDB can be
constructed as needed and linked to specific release
branches of LLVM/Clang.
