We used to create children DIEs for a scope, then check whether ScopeDIE is
null. If ScopeDIE is null, the children DIEs will be dangling. Other DIEs can
link to those dangling DIEs, which are not emitted at all, causing dwarf error.
The current testing case is 4k lines, from MultiSource/BenchMark/McCat/09-vor.

gcc produces false positives for empty braces so turning the warning off.
Instead, turning the warning on for clang so proper warnings aren't missed.

This patch adds support for AArch64 (ARM's 64-bit architecture) to
LLVM in the "experimental" category. Currently, it won't be built
unless requested explicitly.
This initial commit should have support for:
+ Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions
(except the late addition CRC instructions).
+ CodeGen features required for C++03 and C99.
+ Compilation for the "small" memory model: code+static data <
4GB.
+ Absolute and position-independent code.
+ GNU-style (i.e. "__thread") TLS.
+ Debugging information.
The principal omission, currently, is performance tuning.
This patch excludes the NEON support also reviewed due to an outbreak of
batshit insanity in our legal department. That will be committed soon bringing
the changes to precisely what has been approved.
Further reviews would be gratefully received.

it isn't really an AliasAnalysis concept, and ValueTracking has similar things
that it could plausibly share code with some day.

The Attribute::hasAttributes() is kind of meaningless since an Attribute can
have only one attribute. And we would rather people use the 'operator=='
instead of Attribute::hasAttribute().

reference to a pointer, so that it can handle the case where DataLayout
is not available and behave conservatively.

Makefile.config does not have the value for ENABLE_THREADS substituted as the
variable is called LLVM_ENABLE_THREADS within configure.ac. This was pointed
out by zygoloid over IRC.

The AttrBuilder is there to build up multiple attributes. The Attribute class
represents only one attribute at a time. So remove this unnecessary builder
creator method.

register for inline asm. This conforms to how gcc allows for effective
casting of inputs into gprs (fprs is already handled).

Several places were still treating the Attribute object as respresenting
multiple attributes. Those places now use the AttributeSet to represent
multiple attributes.

for example, a one-past-the-end pointer from one global variable may
be equal to the base pointer of another global variable.

As a bonus I put in some extra checks to make sure that we are identifying the
machine word of various Mac OS X/iOS targets appropriately.
