Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

a bug in the inliner still causes the wrong thing to happen at -O2 and above

John McCall e68b8f4dcc At -O0, prefer objc_storeStrong with a null new value to the
combination of a load+objc_release;  this is generally better
for tools that try to track why values are retained and
released.  Also use objc_storeStrong when copying a block
(again, only at -O0), which requires us to do a preliminary
store of null in order to compensate for objc_storeStrong's
assign semantics.

Alexey Samsonov 38e2496497 Transform pattern:

Benjamin Kramer 1ca66919a5 CodeGen: Copy tail padding when we're not dealing with a trivial copy assign or move assign operator.
This fixes a regression from r162254, the optimizer has problems reasoning
about the smaller memcpy as it's often not safe to widen a store but making it
smaller is.

there's something going on there. Remove the unconditional line entry

John McCall 4e8ca4fa14 Significantly simplify CGExprAgg's logic about ignored results:
if we want to ignore a result, the Dest will be null.  Otherwise,
we must copy into it.  This means we need to ensure a slot when
loading from a volatile l-value.

With all that in place, fix a bug with chained assignments into
__block variables of aggregate type where we were losing insight into
the actual source of the value during the second assignment.

Benjamin Kramer 46a72fb741 Dead code eliminate the massive hexagon builtin intrinsic supporting code.

Fariborz Jahanian 6362803cfe block literal irgen: several improvements on naming block
literal helper functions. All helper functions (global
and locals) use block_invoke as their prefix. Local literal
helper names are prefixed by their enclosing mangled function
names. Blocks in non-local initializers (e.g. a global variable 
or a C++11 field) are prefixed by their mangled variable name. 
The descriminator number added to end of the name starts off 
with blank (for first block) and _<N> (for the N+2-th block).

John McCall c84ed6a336 Abstract the emission of global destructors into ABI-specific code
and only consider using __cxa_atexit in the Itanium logic.  The
default logic is to use atexit().

Emit "guarded" initializers in Microsoft mode unconditionally.
This is definitely not correct, but it's closer to correct than
just not emitting the initializer.

Chandler Carruth 8453795255 Revert r153723, and its follow-ups r153728 and r153733.
These patches cause us to miscompile and/or reject code with static
function-local variables in an extern-C context. Previously, we were
papering over this as long as the variables are within the same
translation unit, and had not seen any failures in the wild. We still
need a proper fix, which involves mangling static locals inside of an
extern-C block (as GCC already does), but this patch causes pretty
widespread regressions. Firefox, and many other applications no longer
build.

Lots of test cases have been posted to the list in response to this
commit, so there should be no problem reproducing the issues.
