same way as X86_64_GOT relocations. The 'Load' part of GOTLoad is just an
optimization hint for the linker anyway, and can be safely ignored.
This patch also fixes some minor issues with the relocations introduced while
processing an X86_64_GOT[Load]: the addend for the GOT entry should always be
zero, and the addend for the replacement relocation at the original offset
should be the same as the addend of the relocation being replaced.
I haven't come up with a good way of testing this yet, but I'm working on it.
This fixes <rdar://problem/14651564>.

In addition to storing more useful information in the AST, this
fixes a semantic check in template instantiation which checks whether
the l-paren location is valid.
Fixes PR16903.

This updates clang according to a pending patch for llvm to
rename of the -arm-darwin-use-movt to arm-use-movt to make
it available for all of ARM.
note: please apply this close to the llvm change.

Before this patch this flag is IOS specific, but is also
useful for bare project like bootloaders / kernels etc,
since movw / movt prevents simple relocation. Therefore
make this flag more commonly available.
note: this patch depends on a similiar rename in clang

Rather than going through the whole getOrCreateType machinery to
manifest a type, cut straight to the implementation because we know we
have to do work.
While the previous implementation was sufficient for the two cases
(completeness and required completeness) we have already (the general
machinery could inspect the type for those attributes & go down the full
definition path), a pending change (to emit info for types when we emit
their vtables) won't have that luxury & we'll need to force the creation
rather than relying on the general purpose routine.

r9 is defined as a platform-specific register in the ARM EABI.
It can be reserved for a special purpose or be used as a general
purpose register. Add support for reserving r9 for all ARM, while
leaving the IOS usage unchanged.
Patch by Jeroen Hofstee.

Summary:
We would crash in CodeGen::CodeGenModule::EmitUuidofInitializer
because our attempt to enter CodeGen::CodeGenModule::EmitConstantValue
will be foiled: the type of the constant value is incomplete.
Instead, create an unnamed type with the proper layout on all platforms.
Punt the problem of wrongly defined struct _GUID types to the user.
(It's impossible because the TU may never get to see the type and thus
we can't verify that it is suitable.)
This fixes PR16856.

This is a patch in a longer series of patches to add
capabilities/definitions that are present in the Autotools build chain
and not in the CMake build chain to the CMake build chain.
*NOTE* I am hacking on this in my free time. I will annotate each commit

rhadd = (x+y+1)>>1
Implemented as:
(x>>1) + (y>>1) + ((x&1)|(y&1))
This prevents us having to do assembly addition and overflow detection

(x + y) >> 1 gets changed to:
(x>>1) + (y>>1) + (x&y&1)
Saves us having to do any llvm assembly and overflow checking in the addition.

Summary:
When the -dfsan-debug-nonzero-labels parameter is supplied, the code
is instrumented such that when a call parameter, return value or load
produces a nonzero label, the function __dfsan_nonzero_label is called.
The idea is that a debugger breakpoint can be set on this function
in a nominally label-free program to help identify any bugs in the
instrumentation pass causing labels to be introduced.

When a region is realloc()ed, MallocChecker records whether it was known
to be allocated or not. If it is, and the reallocation fails, the original
region has to be freed. Previously, when an allocated region escaped,
MallocChecker completely stopped tracking it, so a failed reallocation
still (correctly) wouldn't require freeing the original region. Recently,
however, MallocChecker started tracking escaped symbols, so that if it were
freed we could check that the deallocator matched the allocator. This
broke the reallocation model for whether or not a symbol was allocated.
Now, MallocChecker will actually check if a symbol is owned, and only
require freeing after a failed reallocation if it was owned before.

1. The offset range for Thumb1 PC relative loads is [0..1020] and not [-1024..1020]
2. Thumb2 PC relative loads may define the PC, so the restriction placed on target register is removed
3. Removes unneeded alias between "ldr.n" and t1LDRpci. ".n" is actually stripped by both tablegen
and the ASM parser, so this alias rule really does nothing
