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.

This change adds MemorySanitizer annotations to BumpPtrAllocator to
improve report quality.

That function doesn't make sense anymore because there's only one attribute per
Attribute object now.

Fixed a mistake in my previous commit where I changed the wording slightly and forgot to undo the change after changing my mind and deciding to only commit the style changes.

said section.

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.

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