e0deec7fe0 Linker: correctly link in dbg.declare 
This is a re-worked version of r174048.
Given source IR:
call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !14), !dbg !15
we used to generate 
call void @llvm.dbg.declare(metadata !27, metadata !28), !dbg !29
!27 = metadata !{null}

With this patch, we will correctly generate
call void @llvm.dbg.declare(metadata !{i32* %argc.addr}, metadata !27), !dbg !28

Looking up %argc.addr in ValueMap will return null, since %argc.addr is already
correctly set up, we can use identity mapping.

0b0b695442 Add support for emitting a string attribute. 
Attributes that are strings are typically target-dependent attributes. They are
of this form in the IR:

   "attr"
   "attr" = "val"

f01539f6a1 [Dwarf] early exit to avoid creating dangling DIEs 
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.

e2b0519ed8 Add AArch64 as an experimental target. 
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.

37dbbd1577 Remove Attribute::hasAttributes() and make Attribute::hasAttribute() private. 
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().
