Michael Gottesman 41e4ac4224 Filecheckized 2x tests in SimplifyCFG and removed their date prefix to fit with current llvm style for test names.

Bill Wendling b8b16b567c 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.

Eric Christopher 4e3e94c13d Check and allow floating point registers to select the size of the 
register for inline asm. This conforms to how gcc allows for effective
casting of inputs into gprs (fprs is already handled).

Bill Wendling 8594fcbd1a Make sure that the Attribute object represents one attribute only. 
Several places were still treating the Attribute object as respresenting
multiple attributes. Those places now use the AttributeSet to represent
multiple attributes.

Michael Gottesman 606acb7c85 Added a unit test for r173983 that verifies that Target.isiOS() works correctly. 
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.

There are still places which treat the Attribute object as a collection of
attributes. I'm systematically removing them.

Greg Clayton 85e62eca66 expressions + C++11 lambdas == cooooool!!! 
C++11 lambdas that don't capture anything can be used as static callback functions!

Heavily modified this python module to be able to not require a dylib in order to traverse the heap allocations.

Re-implemented the ptr_refs, objc_refs, malloc_info and cstr_refs to use complex expressions that use lambdas to do all static callback function work.

Michael Gottesman 9656405684 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.

Daniel Dunbar a495930c1d [build/clang_darwin] Fix the case reversal in r173465. 
- I got confused by the double negative, the test succends on 10.6, in which
   case we *do* want to perform the filter-out.

Jordan Rose 2da0d1cfd3 Diagnostics: if a line is longer than 4096 characters, don't print it. 
Specifically, don't print snippets, caret diagnostics, or ranges for
lines over 4096 characters. We copy the line around a few times in our
diagnostics machinery, and we have to print a caret line that's just as
long. This uses a lot of memory just to create a poor user experience as
we print out a line much too long for anyone to read...or spend extra
energy trying to fit it to -fmessage-length.

Andrew Trick 89fc5a6627 ...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.
