Chris Lattner 827a270a2a teach GVN to widen integer loads when they are overaligned, when doing an 
wider load would allow elimination of subsequent loads, and when the wider
load is still a native integer type.  This eliminates a ton of loads on 
various benchmarks involving struct fields, though it is somewhat hobbled
by clang not being very aggressive about field alignment.

This is yet another step along the way towards resolving PR6627.

Francois Pichet a1c1352a36 Support &__uuidof(type) as a non type template argument. 
This idiom is used everywhere in MFC/COM code and as such this patch removes hundreds of errors when parsing MFC code with clang.

Example: 
template <class T, const GUID* g = &__uuidof(T)>
class ComTemplate  { };

typedef ComTemplate<struct_with_uuid, &__uuidof(struct_with_uuid)> COM_TYPE;

Of course this is just parsing support. Trying to use this in CodeGen will generate:
error: cannot yet mangle expression type CXXUuidofExpr

Rafael Espindola 2eeee8cfef Add a small temporary hack for producing identical eh_frame sections on OS X. 
This removes one of the main advantages of moving eh_frame to MC, but

John McCall a85af56e66 When block-capturing a variable with a non-trivial destructor, 
make sure to mark the destructor.  This normally isn't required,
because the destructor should have been marked as part of the
declaration of the local, but it's necessary when the variable
is a parameter because it's the call sites that are responsible
for those destructors.

John Wiegley 6242b6a688 Implementation of Embarcadero array type traits 
Patch authored by John Wiegley.

__array_extent(T, Dim).

John Wiegley 65497cce20 t/clang/type-traits 
Patch authored by John Wiegley.

These type traits are used for parsing code that employs certain features of
the Embarcadero C++ compiler.  Several of these constructs are also desired by
libc++, according to its project pages (such as __is_standard_layout).

Rafael Espindola 08704349da Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, and 
give it a bit more responsibility. Also implement it for MachO.

If hacked to use cfi, 32 bit MachO will produce

.cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr

and 64 bit will produce

.cfi_presonality ___gxx_personality_v0

The general idea is that .cfi_personality gets passed the final symbol. It is
up to codegen to produce it if using indirect representation (like 32 bit
MachO), but it is up to MC to decide which relocations to create.

Andrew Trick 29ac7b8858 Fixes PR9730: indvars: An asserting value handle still pointed to this value 
Modified LinearFunctionTestReplace to push the condition on the dead
list instead of eagerly deleting it. This can cause unnecessary
IV rewrites, which should have no effect on codegen and will not be an
issue once we stop generating canonical IVs.
