Amongst other, this will help LTO to correctly handle/honor files
compiled with O0, helping debugging failures.
It also seems in line with how we handle other options, like how
-fnoinline adds the appropriate attribute as well.

Reapplying patch in r272777 which was reverted
because the llvm patch which added support
for generating the mcrr/mcrr2 instructions
from the intrinsic was causing an assertion
failure. This has now been fixed in llvm.

Patch adds intrinsics for mrrc/mrrc2. The
intrinsics for mrrc/mrrc2 return a single
uint64_t to represent two 32 bit values.
The mcrr/mcrr2 intrinsic was changed to
accept a single uint64_t instead of two
32 bit values as the input for consistency.

- Fixed cdp intrinsic to only accept compile time
constant values previously you could pass in a
variable to the builtin which would result in
illegal llvm assembly output

This is mostly a one-time autoconversion of tests that checked assembly after
"-Owhatever" compiles to only run "opt -mem2reg" and check the assembly. This
should make them much more stable to changes in LLVM so they won't break on
unrelated changes.
"opt -mem2reg" is a compromise designed to increase the readability of tests
that check dataflow, while minimizing dependency on LLVM. Hopefully mem2reg is
stable enough that no surpises will come along.
Should address http://llvm.org/PR26815.

in section 10.1, __arm_{w,r}sr{,p,64}.
This includes arm_acle.h definitions with builtins and codegen to support
these, the intrinsics are implemented by generating read/write_register calls
which get appropriately lowered in the backend based on the register string
provided. SemaChecking is also implemented to fault invalid parameters.

This patch implements __builtin_arm_nop intrinsic for AArch32 and AArch64,
which generates hint 0x0, the alias of NOP instruction.
This intrinsic is necessary to implement ACLE __nop intrinsic.

modelling by adding has-side-effects property.

This corrects SVN r212196's naming change to use the proper prefix of
`__builtin_arm_` instead of `__builtin_`.
Thanks to Yi Kong for pointing out the incorrect naming!

This extends the target builtin support to allow language specific annotations
(i.e. LANGBUILTIN). This is to allow MSVC compatibility whilst retaining the
ability to have EABI targets use a __builtin_ prefix. This is merely to allow
uniformity in the EABI case where the unprefixed name is provided as an alias in
the header.

Add support for the remaining hints from the ACLE. Although __dbg is listed as
a hint, it is handled different, so it is not covered by this change.

Use the new generic @llvm.arm.hint hint intrinsic rather than the specialised
@llvm.arm.sevl hint instruction.

Lots of tests are using an explicit target triple w/o first checking that the
target is actually available. Add a REQUIRES clause to a bunch of them. This should
hopefully unbreak bots which don't configure w/ all targets enabled.
