The skipOnLinux decorator wasn't calling the test method correctly (no need to pass in the "self") resulting
in errors on MacOS X for the tests so decorated.

Applied the patch, rather than committing it.

Detect the new fixed clang that properly supports bitfields in objc classes.

Revert r168635 "Step towards implementation of pass manager with doInitialization and doFinalization per module detangled from runOn?? calls, still has temporary code not to break ASAN to be removed when that pass conforms to the proposed model".
It appears to have broken at least one buildbot.

Added in first optimization using fast-math flags to serve as an example for following optimizations. SimplifyInstruction will now try to optimize an fmul observing its FastMathFlags to see if it can fold multiply by zero when 'nnan' and 'nsz' flags are set.

llvm-svn: 168648

llvm-svn: 168647

Added in bitcode enum for the serializing of fast-math flags. Added in the reading/writing of fast-math flags from the OptimizationFlags record for BinaryOps.

llvm-svn: 168646

Added in the ability to read LLVM IR text that contains fast-math flags as a sequence of capital letters separated by spaces in any order. Added in the printing of the fast-math flags in a canonical order, and don't print the other flags when 'fast' is specified, as 'fast' implies all the others.

add a TODO for starting.

Add in getter/setter methods for Instructions, allowing them to be the interface to FPMathOperator similarly to now NUS/NSW is handled.

llvm-svn: 168642

Created FastMathFlags convenience struct for the getting and setting of fast-math flags en masse. Added SubclassOptionalData bitfields and corresponding getters/setters to FPMathOperator for the various fast-math flags.

Patch by Pedro Artigas, with feedback from by Chandler Carruth.

The Function calling thread plan was replacing the stored stop info too soon, causing recursive entry into the
breakpoint StopInfo's PerformAction, which is bad.  Reworked this so that it is now correct.

It currently assumes register numbering and any harmless change in the X86
register naming makes it fail. It's enough to match the register names.

r168627), we no longer need to call the freezeReservedRegs() function a second
time.  Previously, this pass was conservatively adding the FP to the set of
reserved registers, requiring the second update to the reserved registers.

InstCombineLoadStoreAlloca.cpp, which had many issues.
(At least two bugs were noted on llvm-commits, and it was overly conservative.)
Instead, use getOrEnforceKnownAlignment.

This pass was conservative in that it always reserved the FP to enable dynamic
stack realignment, which allowed the RA to use aligned spills for vector
registers.  This happens even when spills were not necessary.  The RA has 
since been improved to use unaligned spills when necessary.

The new behavior is to realign the stack if the frame pointer was already
reserved for some other reason, but don't reserve the frame pointer just
because a function contains vector virtual registers.

Improve diagnostic on C++11 attribute specifiers that appear at wrong syntactic locations around class specifiers.

This change list implemented logic that explicitly detects several combinations of locations where C++11 attribute
specifiers might be incorrectly placed within a class specifier. Previously we emit generic diagnostics like 
"expected identifier" for such cases; now we emit specific diagnostic against the misplaced attributes, this also 
fixed a bug in old code where attributes appear at legitimate locations were incorrectly rejected.

Thanks to Richard Smith for reviewing!
