2fe5911bfe Remove the Attribute::hasAttributes() function. 
That function doesn't make sense anymore because there's only one attribute per
Attribute object now.

section Global Variable so that the style matches the other keywords in
said section.

6968f40e37 Move isKnownNonNull out of AliasAnalysis.h and into ValueTracking.cpp since 
it isn't really an AliasAnalysis concept, and ValueTracking has similar things
that it could plausibly share code with some day.

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().

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.

d1d96ba2d8 Remove the AttrBuilder version of the Attribute::get function. 
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.

b7a478403d Make sure that the Attribute object represents one attribute only.

multiple attributes. Those places now use the AttributeSet to represent
multiple attributes.

1e063570f0 Removed CreateFPExtOrFPTrunc for now until I have the time to get in my vector convert patch. 
What I thought was going to be a quick thing has extended out a little bit in
time *sigh*. So after some thought in order to not cruft up the tree I am
removing this for now since it is the right thing to do.

4699474140 ...in light of recent activity related to llvm.memcpy flags. I want to 
prevent an llvm developer from mistakenly thinking that just because the
intrinsic has volatile flags that volatile operations can be converted
to or folded into them.

Platforms may rely on volatile loads and stores of natively supported
data width to be executed as single instruction. When compiling
C, this expectation likely holds for l-values of volatile primitive
types with native hardware support, but not necessarily for aggregate
types. The frontend upholds these expectations, which are not
specified in the IR.

871181e2e0 Linker: correctly link in dbg.declare 
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.
